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 fully differential next-to-next-to-leading order QED calculation of the process, implemented in the McMule framework to enable precise luminosity measurements for electron-positron colliders with center-of-mass energies up to a few GeV.
The DAMSA conceptual design white paper proposes a novel short-baseline accelerator experiment utilizing the PIP-II LINAC to probe MeV-to-sub-GeV dark-sector messengers and rare Standard Model signals by overcoming beam-dump sensitivity limits with a compact detector, a strategy whose feasibility will be validated through the proposed Little DAMSA Path-Finder (LDPF) proof-of-concept experiment.
This study employs a cosmological model-independent artificial neural network approach to reconstruct angular-diameter distances from localized Fast Radio Bursts and compare them with Type Ia supernova luminosity distances, finding no statistically significant evidence for deviations from the cosmic distance-duality relation.
This paper computes relativistic corrections to gluon fragmentation into heavy quarkonium states within the NRQCD framework, revealing that - mixing is required to handle infrared divergences and that substantial negative corrections significantly impact production predictions at the LHC.
This paper proposes a non-holomorphic modular scotogenic model with tri-resonant leptogenesis that successfully generates baryogenesis at the low scale of GeV for both normal and inverted neutrino mass hierarchies, while predicting specific neutrino oscillation parameters and being constrained by cosmological data that currently disfavors the inverted hierarchy scenario.
This paper demonstrates that a future 3 TeV muon collider with integrated luminosities of 1–4 ab⁻¹ can discover neutral scalar states in the 200–400 GeV mass range within the -symmetric Three Higgs Doublet Model by analyzing Higgs pair production leading to and final states with significance.
This paper proposes a thermal model incorporating a common local spin equilibrium for spin-1/2 and spin-1 particles to explain the simultaneous longitudinal polarization of hyperons and positive spin alignment of vector mesons in heavy-ion collisions, noting that while the model reproduces observed trends, it currently lacks full quantitative agreement with experimental data.
This paper proposes that Ultra-High Energy Cosmic Rays above 40 EeV are primarily composed of fragile light nuclei (such as He, D, Li, and Be) originating from nearby extragalactic sources like CenA and NGC 253, a model that explains observed sky anisotropies, the absence of signals from distant regions like Virgo, and the presence of event multiplets due to nuclear fragmentation.
By modeling resonance decay effects on pion and kaon-proton correlations in 13 TeV pp collisions, this study demonstrates that a universal, collectively scaling primordial emission source exists for all hadron species in small collision systems at the LHC.
This study presents new constraints on a string-motivated Chameleon dark energy model, revealing a mild preference for a non-zero dark sector coupling () and weak evidence favoring the interaction over CDM when combining Planck, DESI DR2, and SH0ES data, despite the model's asymptotic return to limiting the strength of this evidence.
