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 demonstrates that advanced Deep Learning methodologies applied to low-level calorimeter data can achieve a statistical significance of approximately 4.5σ in detecting heavy CP-even Higgs boson chain decays () produced via Vector Boson Fusion within the Next-to-Minimal Supersymmetric Standard Model at the LHC with 300 fb of integrated luminosity.
This paper introduces the IdylliQ model of quarkyonic matter, which describes a crossover from baryonic to quark matter driven by quark saturation to explain the stiffening of dense matter and the mitigation of the hyperon softening problem in neutron stars.
This paper derives a two-species Schrödinger-Poisson-Yukawa system for dark-sector fermions within an orbital-free density-functional framework, demonstrating that the Bohm potential induces a species-dependent surface-energy correction that governs the mass-radius relations of self-gravitating quantum stars and offers a predictive, first-principles method to constrain dark-fermion masses through observable astrophysical signatures.
This paper investigates the dependence and absorptive imaginary parts of the tau lepton's anomalous magnetic and electric dipole moments within the SMEFT and 2HDM frameworks, demonstrating that combining measurements from Belle II and the Super Tau-Charm Facility can significantly improve current bounds and uniquely probe the energy evolution of these form factors.
This paper extends the study of Critical Unstable Qubits (CUQs) by employing density matrix formalism to characterize their unique indefinite anharmonic oscillations and coherence-decoherence dynamics, providing the first explicit geometric constructions of their trajectories within and on the Bloch sphere to identify stationary points and discuss implications for particle cosmology and quantum simulations.
This paper presents quantum-mechanical calculations demonstrating that coherent bremsstrahlung emission overwhelmingly dominates over incoherent emission in Sn+Sn scattering at 25 MeV/u, a behavior that contrasts sharply with proton-nucleus collisions and reveals a new quantum regime for studying coherent effects in heavy-ion reactions.
This paper investigates the exclusive semileptonic decays of using a light-front quark model that incorporates nonvalence contributions, yielding branching ratios consistent with recent BESIII measurements and demonstrating the significant role of these nonvalence effects in such baryon decays.
This paper utilizes the superfield formalism to demonstrate that color confinement in QCD arises from BRST-bound states that render gluons and quarks massive dipole fields, a mechanism the authors propose could similarly resolve the unitarity violation caused by massive ghosts in quadratic gravity.
This paper demonstrates that in a GUT-inspired gauge-Higgs unification model on a Randall-Sundrum warped space, the total gauge anomalies, despite flowing with the Aharonov-Bohm phase, become universal and independent of bulk mass parameters, ensuring anomaly cancellation within each generation even when the phase is non-zero.
This paper presents a validated implementation of the ATLAS triple Higgs to six -jets search in CheckMATE and Rivet, utilizing it to establish exclusion limits for Standard Model and TRSM benchmarks and to project High Luminosity LHC sensitivity under various systematic uncertainty scenarios.
