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 presents a general relativistic framework for calculating the energy deposition and heating of compact stars by directional particle beams, moving beyond traditional isotropic dark matter assumptions to analyze scenarios such as boosted dark matter from blazars interacting with white dwarfs and neutron stars.
This paper demonstrates that quantum coherence in top-quark pair production at the LHC, quantified via the -norm of the reconstructed spin density matrix, exhibits a non-monotonic dependence on kinematic variables and aligns with Standard Model predictions, thereby establishing it as a viable precision observable for probing spin dynamics at hadron colliders.
This paper investigates cosmological gravitational particle production of dark matter in two-field inflation models, demonstrating that negative field-space curvature can significantly enhance the production of minimally coupled spectator scalars while identifying conformally coupled scenarios as a minimally constrained mechanism for purely gravitational dark matter.
This paper introduces a systematic method for constructing one-parameter modular models where charged-fermion mass matrices are fixed by single modular invariant contractions, demonstrating that such highly constrained frameworks can yield exact high-scale mass relations compatible with low-energy data after renormalization-group evolution and threshold effects.
This paper generalizes the ultrarelativistic freeze-out (UFO) mechanism for dark matter to arbitrary reheating temperature profiles, demonstrating that gravitational particle production at the onset of reheating significantly alters the parameter space and relic abundance, a phenomenon termed gravitational UFO (GUFO).
This paper investigates how scalar non-standard neutrino interactions induce pseudo-Dirac behavior that alters the flavor composition and energy spectrum of high-energy astrophysical neutrinos, using current IceCube data and projected IceCube-Gen2 capabilities to establish new constraints on Yukawa couplings and scalar masses for ultra-light mediators.
This paper proposes a calibrated framework demonstrating that coherent production at the Electron-Ion Collider can competitively measure neutron skins and constrain symmetry energy, provided that precision is achieved through the calibration of small- gluon densities rather than relying solely on luminosity.
This paper proposes a halo-independent framework utilizing quantum sensors with sub-eV thresholds to directly detect sub-GeV dark matter and reconstruct the local dark matter velocity distribution by separating detector-specific responses from a universal halo function.
This paper investigates Higgs scattering in the unbroken electroweak phase within the SMEFT framework by treating the Higgs doublet as a qubit to quantify momentum-isospin entanglement via von Neumann entropy and concurrence, revealing how dimension-6 and dimension-8 operators influence entanglement growth, interference-induced cancellations, and suppression conditions that correlate with positivity bounds.
This paper investigates the rare weak decay of the positronium ion () into an electron and a muon neutrino-antineutrino pair via a virtual boson, calculating its decay rate and finding a branching ratio comparable to that of the weak decay of ortho-positronium.
