abstract
In this work, we reinterpret ATLAS and CMS dijet resonance searches to set robust constraints on all hypothetical tree-level scalar and vector mediators with masses up to 5 TeV, assuming a diquark or a quark-antiquark coupling with an arbitrary flavor composition. To illustrate the application of these general results, we quantify the permissible size of new physics in $\bar B_q\to D_q^{(*)+} \,\{\pi, K\}$ consistent with the absence of signal in dijet resonance searches. Along the way, we perform a full SMEFT analysis of the aforementioned non-leptonic $B$ meson decays at leading-order in $\alpha_s$. Our findings uncover a pressing tension between the new physics explanations of recently reported anomalies in these decays and the dijet resonant searches. The high-$p_T$ constraints are crucial to drain the parameter space consistent with the low-$p_T$ flavor physics data.

Towards a Global Analysis of the $b\to c\bar{u} q$ Puzzle
New three-particle QCD kernels for the full Weak Effective Theory basis plus a first six-coupling global fit show that the b to c u q puzzle favors four-operator new-physics models over six-operator ones.

$B$-meson decay width up to $1/m_b^3$ corrections within and beyond the Standard Model
Complete analytic HQE matching coefficients for B-meson decay widths up to 1/m_b^3 are derived for generic new-physics operators, including previously missing weak-annihilation terms.

In Search of an Invisible $Z^\prime$
Anomaly cancellation forces every Z-pole-invisible, anomaly-free Z' to couple to valence quarks and at least two charged lepton flavours, ensuring LHC coverage.

Flavor constraints from $pp\to Vh$ and $pp\to VW$ at the LHC
LHC data on pp→Vh and pp→VW yield general-flavor SMEFT constraints that will become competitive with flavor tests of the Cabibbo-angle anomaly at the HL-LHC.

Weak decays of $B_s$ meson in self-consistent covariant light-front approach
A self-consistent light-front quark model calculation gives B_s to P(V) form factors and decay observables, with semileptonic results consistent with lattice QCD and LHCb but nonleptonic predictions requiring fitted e...
