The pith

Exotic Higgs decays to a light pseudoscalar that decays into an electron-muon pair can set stronger limits on lepton flavor violation than low-energy precision tests.

A machine-rendered reading of the paper's core claim, the machinery that carries it, and where it could break.

The paper proposes two new collider signatures for electron-muon flavor violation that arise when the 125 GeV Higgs boson decays to a light pseudoscalar, which in turn decays to an electron-muon pair. These processes produce relatively clean multilepton final states at the LHC. Working in the type-III two-Higgs-doublet model as a benchmark, the authors map out parameter regions where the pseudoscalar remains viable and show that the resulting signatures can constrain the relevant flavor-violating couplings more tightly than existing low-energy measurements. A sympathetic reader would care because this suggests collider experiments can access new physics in the lepton sector that precision experiments have not yet ruled out.

Core claim

In the type-III two-Higgs-doublet model a light pseudoscalar can be produced in the decays of the 125 GeV Higgs and subsequently decay to an electron-muon pair, generating multilepton signatures whose observation or non-observation at the LHC yields tighter bounds on the lepton-flavor-violating couplings than current low-energy precision data.

What carries the argument

The light pseudoscalar that is produced in exotic Higgs decays and then decays to an electron-muon pair, generating the proposed multilepton signatures.

If this is right

  • Multilepton signatures from Higgs-to-pseudoscalar decays become a practical search channel at the LHC.
  • Parameter space in the type-III two-Higgs-doublet model can be further restricted by requiring the pseudoscalar to remain consistent with both low-energy and collider bounds.
  • Collider-based limits on lepton-flavor-violating Higgs couplings can surpass those from precision measurements in regions where the light pseudoscalar is present.
  • The same decay chain can be used to test other extended Higgs models that predict light pseudoscalars.

Where Pith is reading between the lines

These are editorial extensions of the paper, not claims the author makes directly.

  • Similar exotic-decay searches could be applied to other lepton-flavor-violating channels such as muon-tau or electron-tau at future colliders.
  • If the light pseudoscalar is discovered, its decay branching ratios would directly measure the size of the flavor-violating Yukawa couplings.
  • The approach links Higgs phenomenology at the LHC to the broader question of whether lepton flavor violation is tied to an extended scalar sector.

Load-bearing premise

A light pseudoscalar must exist in viable regions of the type-III two-Higgs-doublet model and must have a large enough branching ratio to electron-muon pairs to produce observable multilepton events.

What would settle it

An LHC search for the proposed multilepton final states from Higgs production that finds no excess over Standard Model backgrounds across the identified parameter space would falsify the claim that these signatures provide stronger constraints.

read the original abstract

In this paper, we propose two novel signatures of Higgs decays to search for electron-muon flavor violation. These signatures arise from the presence of a light pseudoscalar into which the 125-GeV Higgs boson decays. The pseudoscalar subsequently decays into an electron-muon pair, leading to multilepton final states, which are relatively clean signatures to search for at the LHC. As a benchmark, we consider the type-III Two-Higgs-doublet-model. We analyze both low-energy and collider constraints on the model and identify regions of parameter space where the light pseudoscalar is viable. Our proposed signatures yield stronger constraints on the lepton flavor violating couplings than current low-energy precision measurements. Taken together, our findings suggest that collider-based probes of exotic Higgs decays provide a powerful complement to precision experiments in the quest to uncover new physics.

Referee Report

2 major / 2 minor

Summary. The manuscript proposes two novel multilepton signatures at the LHC for electron-muon flavor violation arising from exotic 125 GeV Higgs decays to a light pseudoscalar A (h → AA or h → ZA) followed by A → eμ in the type-III Two-Higgs-Doublet Model. After imposing low-energy and collider constraints, viable regions of parameter space are identified, and the authors claim that these collider probes set stronger limits on the LFV Yukawa couplings than existing precision measurements such as μ → eγ or μ → 3e.

Significance. If the quantitative demonstration holds, the work would usefully complement low-energy LFV searches by exploiting the clean multilepton final states accessible at the LHC. The approach is grounded in a standard model extension and could motivate dedicated experimental analyses, but its impact hinges on showing that the product BR(h → A) × BR(A → eμ) remains large enough in the surviving parameter space to improve existing bounds.

major comments (2)
  1. [§4 and §5] §4 (viable regions) and §5 (collider projections): the central claim that the proposed signatures yield stronger constraints on the LFV couplings than low-energy measurements is not supported by explicit results. No plots or tables quantify the product BR(h → A) × BR(A → eμ) after all constraints (including μ → eγ) are applied, nor is a comparison to current experimental limits provided. Without this, it is impossible to verify whether the collider reach exceeds existing bounds in the identified windows.
  2. [§3.2] §3.2 (A → eμ branching ratio): the same off-diagonal Yukawa entries control both the low-energy LFV rates and the A → eμ width. The manuscript does not demonstrate that, once μ → eγ is satisfied, the residual BR(A → eμ) is not suppressed below the level needed for observable multilepton signals (e.g., by phase space or competing modes such as A → τμ or A → bb).
minor comments (2)
  1. [Figure 2] Figure 2: the color scale and axis labels for the viable regions are difficult to read; adding a legend for the excluded versus allowed points would improve clarity.
  2. [§2] Notation: the definition of the LFV Yukawa matrix elements (e.g., Y_{eμ}) should be stated explicitly in the text rather than only in an appendix equation.

2 responses · 0 unresolved

We thank the referee for the careful reading and constructive feedback. We have revised the manuscript to provide the missing quantitative support for our claims on the collider reach relative to low-energy bounds, and to clarify the branching ratio behavior in the viable parameter space. Point-by-point responses follow.

read point-by-point responses

  1. Referee: [§4 and §5] the central claim that the proposed signatures yield stronger constraints on the LFV couplings than low-energy measurements is not supported by explicit results. No plots or tables quantify the product BR(h → A) × BR(A → eμ) after all constraints (including μ → eγ) are applied, nor is a comparison to current experimental limits provided.

    Authors: We agree that explicit quantification is required to substantiate the claim. In the revised manuscript we have added a new figure in §5 that displays the product BR(h → AA/ZA) × BR(A → eμ) over the viable regions after all low-energy and collider constraints, including μ → eγ, are imposed. A direct comparison to the current experimental limits from μ → eγ and μ → 3e is included, showing that the LHC multilepton channels can probe smaller LFV Yukawa entries in the surviving windows. The text in §4 and §5 has been updated to reference these results. revision: yes

  2. Referee: [§3.2] the same off-diagonal Yukawa entries control both the low-energy LFV rates and the A → eμ width. The manuscript does not demonstrate that, once μ → eγ is satisfied, the residual BR(A → eμ) is not suppressed below the level needed for observable multilepton signals (e.g., by phase space or competing modes such as A → τμ or A → bb).

    Authors: We thank the referee for highlighting this point. The revised §3.2 now contains explicit branching-ratio calculations for the light pseudoscalar. For the mass range considered (m_A below the bb threshold and with the type-III mixing structure), phase space and coupling hierarchies suppress competing modes such as A → τμ and A → bb relative to A → eμ. We show that BR(A → eμ) remains at the few-percent level or higher in the regions that survive μ → eγ, sufficient to produce observable multilepton rates. A supplementary plot of the branching fractions versus the relevant Yukawa parameters has been added. revision: yes

Circularity Check

0 steps flagged

No circularity: phenomenological analysis grounded in external constraints

full rationale

The paper starts from the type-III 2HDM Lagrangian, computes branching ratios for h→A and A→eμ using standard expressions, then applies independent external constraints (μ→eγ, μ→3e, collider limits) to delineate viable parameter space. Within those regions it evaluates the product BR(h→A)×BR(A→eμ) against LHC multilepton sensitivity. No quantity is defined in terms of itself, no fitted input is renamed a prediction, and no load-bearing step reduces to a self-citation or ansatz imported from the authors' prior work. The central claim remains externally falsifiable and does not collapse to the paper's own inputs by construction.
