The pith

Updated heavy quark expansion confirms lifetime hierarchy for doubly charmed baryons and matches recent experimental value for Ξ_cc++.

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

The paper recalculates lifetimes of doubly charmed baryons by extending the heavy quark expansion to include next-to-leading-order strong coupling terms and additional power corrections in the inverse charm quark mass. These refinements produce a clear ordering in which the Ξ_cc+ baryon decays fastest, the Ω_cc+ lives longer, and the Ξ_cc++ lives longest. The absolute prediction for the longest lifetime falls inside the range reported by the LHCb experiment. Numerical ratios of the two shorter lifetimes to the longest one are also extracted. The results show that the ordering survives once the new correction terms are added.

Core claim

Within the heavy quark expansion, including available NLO α_s contributions and newly-computed terms in the 1/m_c series, the lifetimes satisfy τ(Ξ_cc+) < τ(Ω_cc+) < τ(Ξ_cc++), with τ(Ξ_cc++) = 0.32 ± 0.05 +0.08/-0.07 ps consistent with the recent LHCb determination, and the ratios τ(Ξ_cc+)/τ(Ξ_cc++) = 0.22 ± 0.05 ± 0.04 and τ(Ω_cc+)/τ(Ξ_cc++) = 0.52 ± 0.13 +0.03/-0.02.

What carries the argument

Heavy quark expansion for baryon lifetimes, incorporating NLO perturbative QCD corrections and 1/m_c power corrections.

If this is right

  • The lifetime ordering survives after the new 1/m_c terms are added.
  • The Ξ_cc++ lifetime is predicted to be 0.32 ps with stated uncertainties.
  • The ratio τ(Ξ_cc+)/τ(Ξ_cc++) is 0.22 with combined uncertainties.
  • The ratio τ(Ω_cc+)/τ(Ξ_cc++) is 0.52 with combined uncertainties.

Where Pith is reading between the lines

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

  • More precise data on the shorter-lived states would directly test the extracted ratios.
  • The same expansion framework could be applied to lifetimes of other singly or doubly heavy baryons to check consistency across the spectrum.
  • If the hierarchy holds, it strengthens the case for using the expansion even when the heavy quark mass is only a few times the QCD scale.

Load-bearing premise

The heavy quark expansion remains reliable for charm quarks once the newly computed 1/m_c terms are included, so that higher-order contributions do not invalidate the numerical results or the stated hierarchy.

What would settle it

A measurement showing that the lifetime of Ξ_cc++ lies well outside 0.32 ps or that the ordering τ(Ξ_cc+) < τ(Ω_cc+) < τ(Ξ_cc++) is reversed.

read the original abstract

We present updated predictions for lifetimes of doubly charmed baryons, within the heavy quark expansion, including available NLO $\alpha_s$ contributions and newly-computed terms in the $1/m_c$ series. Our improved results confirm the expected hierarchy $$\tau(\Xi_{cc}^{+}) < \tau(\Omega_{cc}^{+}) < \tau(\Xi_{cc}^{++}) \,, $$ while the predicted lifetime $\tau(\Xi_{cc}^{++}) = 0.32 \pm 0.05 ^{+0.08}_{-0.07} \,\textrm{ps} $ is consistent with the recent LHCb determination. We provide predictions for the lifetime ratios of the $\Xi_{cc}^{+}$ and $\Omega_{cc}^+$ baryons relative to the $\Xi_{cc}^{++}$ baryon, namely $\tau(\Xi_{cc}^{+})/\tau(\Xi_{cc}^{++})=0.22\pm 0.05\pm 0.04$ and $\tau(\Omega_{cc}^{+})/\tau(\Xi_{cc}^{++})=0.52\pm 0.13^{+0.03}_{-0.02}$.

Referee Report

1 major / 0 minor

Summary. The manuscript updates lifetime predictions for the doubly charmed baryons Ξ_cc^+, Ω_cc^+, and Ξ_cc++ in the heavy-quark expansion, incorporating NLO α_s corrections and newly computed 1/m_c terms. It reports confirmation of the hierarchy τ(Ξ_cc^+) < τ(Ω_cc^+) < τ(Ξ_cc++), a central value τ(Ξ_cc++) = 0.32 ± 0.05 +0.08/-0.07 ps consistent with recent LHCb data, and the ratios τ(Ξ_cc^+)/τ(Ξ_cc++) = 0.22 ± 0.05 ± 0.04 and τ(Ω_cc^+)/τ(Ξ_cc++) = 0.52 ± 0.13 +0.03/-0.02.

Significance. If the central results hold, the work supplies improved theoretical benchmarks for doubly charmed baryon lifetimes that can be directly confronted with LHCb measurements and future data. The explicit inclusion of newly computed 1/m_c terms represents a concrete advance over prior literature that stopped at lower orders in the expansion.

major comments (1)
  1. [Abstract] Abstract: the quoted uncertainties and the strict lifetime hierarchy rest on the assumption that the heavy-quark expansion truncated after the new 1/m_c terms is already reliable for m_c ≈ 1.5 GeV. The manuscript supplies no explicit estimate or bound on the size of the omitted 1/m_c² and higher contributions (or on possible violations specific to the two-charm system), which directly affects whether the reported ±0.05 and asymmetric errors can be taken at face value.

Referee: [Abstract] Abstract: the quoted uncertainties and the strict lifetime hierarchy rest on the assumption that the heavy-quark expansion truncated after the new 1/m_c terms is already reliable for m_c ≈ 1.5 GeV. The manuscript supplies no explicit estimate or bound on the size of the omitted 1/m_c² and higher contributions (or on possible violations specific to the two-charm system), which directly affects whether the reported ±0.05 and asymmetric errors can be taken at face value.

    Authors: We agree that the manuscript does not supply an explicit quantitative bound on the omitted 1/m_c² and higher terms. A complete calculation of these contributions is a major effort outside the scope of the present update, which incorporates the newly computed 1/m_c corrections. The quoted uncertainties are obtained from parameter variations and the magnitude of the included terms; they do not constitute a rigorous truncation-error estimate. We will add a short discussion in the conclusions section on the expected size of higher-order effects, drawing on the convergence pattern seen in the computed series and on analogous results for singly charmed baryons. This addition will also note the absence of a dedicated two-charm-system analysis. The abstract itself will not be altered beyond a possible clarifying phrase. Revision will therefore be partial. revision: partial

Circularity Check

0 steps flagged

No significant circularity; derivation uses external inputs and new computations

full rationale

The paper computes new 1/m_c terms within the heavy-quark expansion and combines them with NLO alpha_s contributions to obtain lifetime predictions and ratios. These predictions rely on non-perturbative matrix elements and parameters taken from separate literature or lattice calculations, which constitute independent external benchmarks rather than self-derived quantities. The stated hierarchy is presented as theoretically expected rather than derived from the present fit. No equations reduce by construction to the paper's own inputs, no fitted parameters are relabeled as predictions, and no load-bearing self-citations or uniqueness theorems from the same authors are invoked. The numerical result for tau(Xi_cc++) is directly compared to external LHCb data. The derivation chain therefore remains self-contained against external benchmarks.

Axiom & Free-Parameter Ledger

2 free parameters · 1 axioms · 0 invented entities

The calculation rests on the heavy quark expansion framework whose validity for charm is an assumption, plus perturbative QCD corrections whose coefficients are taken as standard; non-perturbative parameters are expected to be imported from other sources. No new entities are postulated.

free parameters (2)
  • non-perturbative matrix elements in HQE
    Standard in lifetime calculations; values typically fitted to data or lattice results from other decays.
  • higher-order 1/m_c coefficients
    Newly computed but still part of the expansion whose convergence depends on the charm mass scale.
axioms (1)
  • domain assumption Heavy quark expansion converges sufficiently for charm quarks when NLO α_s and new 1/m_c terms are included
    Invoked by the choice of method and the claim that the hierarchy and numerical values are reliable.
