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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper proposes a novel Hamiltonian framework for chiral gauge theories on a disk boundary by introducing an alternative gauge field extension into the bulk that preserves non-perturbative topological features while enabling exact functional expressions suitable for future quantum simulations.
This paper proposes using the SHiP experiment to probe CP violation in GeV-scale dark scalar bosons by analyzing the ratio of three-meson to two-meson decay events, which arise from pseudoscalar and scalar couplings respectively, alongside complementary two-muon and di-photon channels.
This paper investigates how the finite size of dark matter particles affects p-wave Sommerfeld resonances, finding that while such size suppresses the resonance strength compared to point-like scenarios, the p-wave contribution can still dominate over the s-wave and maintain similar velocity dependence, with nugget dark matter behaving more like the point-like case.
This paper investigates the complementarity between collider searches and gravitational-wave observations in a classically scale-invariant extension of the Standard Model, demonstrating that gravitational waves from tachyonic phase transitions can probe regions of small gauge couplings and heavy bosons that are inaccessible to current and future collider experiments.
This paper quantifies the contribution of color entanglement to TMD factorization breaking in nearly back-to-back dijet production by demonstrating that crossed gluon diagrams introduce an additional term equal to times the standard hard coefficient, thereby distinguishing the collinear twist-three result from the TMD-factorization prediction.
This paper analytically demonstrates for the first time that the thermal photon production rate from a hot and dense quark-gluon plasma is independent of the intermediate momentum cutoff even in the presence of a nonzero quark chemical potential, thereby resolving a long-standing issue and providing a generalized expression suitable for relativistic hydrodynamic simulations.
This paper investigates neutrino oscillations within a static, spherically symmetric spacetime supported by ultrarelativistic matter (the Tolman VI metric) by analytically computing eikonal and spinoptics phases to disentangle gravitational and electroweak effects, ultimately proposing a method to identify naked singularities through flavor-equilibrium and quantum-mechanical scrambling of neutrinos.
This paper presents the first systematic investigation of direct Urca processes in neutron star cooling simulations, demonstrating that these new neutrino emission channels significantly accelerate thermal evolution and offer a viable explanation for neutron stars with unusually low surface temperatures.
This paper proposes a non-perturbative formulation of quantum gravity in asymptotically flat spacetimes by demonstrating that Witten's cubic open string field theory on unstable D-branes dynamically generates the closed string S-matrix through gauge-invariant operators, thereby establishing a concrete flat-space analogue of the AdS/CFT correspondence.
This paper predicts that the open-charm decays of the narrow states are dominated by quark-interchange mechanisms favoring over final states, with specific spin-dependent width hierarchies that can serve as discriminators for the assignments of the and resonances, while pion-exchange contributions remain sensitive to model parameters.
