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 that strongly-interacting dark sectors can be probed by detecting distinctive absorption features in the cosmic neutrino energy spectrum, caused by the resonant production of dark vector mesons when high-energy neutrinos scatter off the cosmic neutrino background, a signature potentially observable by future telescopes like IceCube-Gen2 Radio.
This paper presents the first exact computation of the two-loop QCD amplitude at leading colour for the associated production of a top-anti-top pair and a W boson, utilizing a novel strategy involving special functions and finite field techniques to overcome elliptic function obstacles and derive the inclusive cross-section at next-to-next-to-leading order.
This paper proposes that microscopic black holes formed by dark matter accumulation in neutron stars can emit long-lived dark sector particles via Hawking radiation, which escape the star and decay into detectable high-energy neutrinos, photons, or charged particles, offering unique spectral and angular signatures to distinguish this mechanism from dark matter annihilation.
This paper demonstrates that the failure of the rule in and decays, particularly in the channel, can be explained by an effective chiral framework incorporating flavor breaking and electromagnetic effects, which renders the previously proposed vector glueball mixing scenario indistinguishable and suggests the discrepancy arises from additional contributions to amplitudes rather than a specific suppression in .
This paper proposes that a cosmic-ray boosted dark matter model featuring a MeV pseudoscalar mediator with couplings can explain the unexplained 248 keV event observed by the LZ collaboration through spin-dependent interactions, while avoiding the constraints of low-energy events that challenge contact interaction approaches.
This paper proposes that the 248 keV nuclear-recoil event observed by the LUX-ZEPLIN (LZ) Collaboration can be explained by composite inelastic dark matter, where a dimension-ten operator splits a 1 TeV dark baryon into two Majorana states via endothermic scattering mediated by a leptophobic vector, yielding a cross-section consistent with LZ data and existing experimental constraints.
Using Gaussian random potentials to model inflationary landscapes, this paper demonstrates that multi-stage inflationary trajectories—characterized by multiple shorter inflation periods separated by transient departures from slow roll—are a substantial and increasingly common occurrence as field-space dimensionality increases, challenging the standard assumption that single-stage inflation is the dominant outcome.
This paper presents the first constraints on QCD axion dark matter in the 0.1–4 eV mass range by analyzing James Webb Space Telescope blank-sky observations, thereby establishing a new method for repurposing astrophysical missions to constrain axion-photon coupling.
This paper demonstrates that LISA observations of extreme mass-ratio inspirals in dense dark matter environments can distinguish neutron stars from black holes and constrain neutron star equations of state by leveraging the relativistic dynamical-friction force, provided the signal-to-noise ratio exceeds approximately 120.
This paper analyzes how soft versus stiff nuclear equations of state influence hybrid star properties, demonstrating that a low-density onset of stiff quark matter in binary hybrid stars best reconciles GW170817 and NICER observations while clarifying the role of nuclear symmetry energy.
