This paper proposes a general method for calculating kinematic limits in high-energy physics by identifying the vanishing of Lorentz invariants analogous to Cayley-Menger determinants, a technique applicable to processes involving lost particles like neutrinos and useful for suppressing background.
This paper investigates the decay using a coupled-channel framework and demonstrates that including the elusive resonance with significantly improves the theoretical description of experimental data from Belle and BESIII.
This paper extends the RI/SMOM renormalization scheme to semi-leptonic operators by utilizing chirally symmetric massless QCD to relate them to protected vector currents, demonstrating the equivalence of a new family of projectors with recent results relevant for calculating Wilson coefficients.
This paper analyzes scalar-sector contributions to oblique parameters within the minimal 331RHN model, demonstrating that the parameter imposes a dominant constraint that limits the symmetry-breaking scale to approximately 10 TeV.
This paper proposes a parasitic high-energy polarized gamma-ray facility at FCC-ee using Compton backscattering to achieve a four- to seven-fold improvement in precision for measuring the polarized gluon distribution in the medium- region through open-charm photoproduction.
This paper investigates resonant triple Higgs production within the Next-to-minimal Two Higgs Doublet Model (N2HDM), demonstrating that interference effects and additional decay channels significantly alter kinematic distributions and necessitate fully differential studies over simplified approximations to accurately probe extended Higgs sectors at the LHC.
This paper proposes that a simple dissipative dark energy scenario, where even weak dissipation of the quintessence field occurs, can explain the DESI observations of an evolving dark energy that crosses the phantom divide without requiring pathological phantom-like dynamics.
This paper employs heavy meson effective field theory with effective spin-symmetry-breaking corrections to analyze excited charm-strange meson decays, successfully constraining mixing angles, validating a mixed assignment for the and states to resolve width discrepancies, and providing predictive decay patterns for higher-mass resonances.
This paper utilizes the SFitter global analysis framework within an effective quantum field theory approach to interpret current permanent electric dipole moment (EDM) measurements via a hadronic-scale Lagrangian, revealing that while some parameters are well-constrained, others require more high-precision data and that theory uncertainties can be managed within the analysis.
This paper extends the holographic V-QCD model by incorporating a charged scalar field to describe quark pairing, revealing a phase diagram with a second-order transition to color superconductivity at temperatures up to ~30 MeV, though the formation of homogeneous paired phases is found to be subdominant to previously discovered modulated phases.
