Hep-Ph explores the fundamental forces that govern how particles interact and behave at the smallest scales imaginable. This field bridges the gap between theoretical predictions and experimental reality, helping scientists understand the building blocks of our universe without getting lost in complex mathematics. Whether investigating the Higgs boson or searching for new physics beyond current models, these studies push the boundaries of human knowledge about matter and energy.

This paper investigates how collider and non-collider probes can constrain the reheating temperature, dark matter mass, and interaction scale of a scenario where dark matter transitions from WIMP to FIMP production via p-wave suppressed interactions, demonstrating that collider experiments are uniquely powerful in constraining derivative operators that are weakly limited by astrophysical observations.
Using the functional renormalization group, this study demonstrates that in QCD-like theories, a $CP$-violating four-fermion interaction becomes relevant in the chirally broken phase while the running of the -parameter is strongly suppressed toward the infrared in the presence of finite quark mass, thereby clarifying how strong-$CP$ effects generated at high energies are transferred to low-energy physics.
Using QCD sum rules, this study investigates the hadronic tensor molecule , calculating its mass and decay width to propose it as a viable candidate for the experimentally observed resonance .
This paper presents an exact analytical calculation of fermionic bubble loop contributions to cosmological collider signals using parallel spectral and Mellin-Barnes methods, revealing that Yukawa interactions with the inflaton yield a vanishing bispectrum due to a field redefinition of tree-level counterparts.
This paper investigates how modular symmetry in magnetized compactifications is violated as a group-like symmetry due to incomplete multiplet representations arising from Scherk-Schwarz phases, yet continues to govern coupling terms through the appearance of modular forms as coupling constants.
This paper analyzes the sensitivity of current and future collider observables to individual top-quark SMEFT operators using data from the Tevatron, LEP, and LHC Run 2, alongside HL-LHC and future lepton collider projections, to identify the most constraining measurements and highlight expected improvements in sensitivity.
This paper presents the first extraction of the unpolarised gluon transverse-momentum-dependent parton distribution from LHC Higgs-boson production data by fitting ATLAS and CMS measurements within a TMD factorisation framework that includes NLL accuracy and linearly polarised gluon contributions.
This paper demonstrates that the pericentre precession of the LAGEOS II satellite can be used to constrain the mass and couplings of quadratically coupled ultralight dark matter scalars, offering a unique probe for parameter space where existing satellite and tabletop experiments are ineffective.
This paper extends the topological diagram approach to charmed baryon decays into baryons and vector mesons by incorporating the Korner-Pati-Woo theorem to derive symmetry relations, extract form factors from experimental data, and predict branching fractions and polarization observables, revealing the significant role of tensor couplings in these processes.
This study utilizes large-volume lattice QCD simulations at the flavor-symmetric SU(3) point to identify bound states corresponding to the , , and resonances, subsequently employing Unitary Chiral Perturbation Theory to trace their pole trajectories to the physical point.
