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 study employs a physics-informed machine learning framework to determine field-dependent Nambu-Jona-Lasinio model parameters, specifically the running coupling constant and quark anomalous magnetic moment, by fitting lattice QCD data to successfully reproduce the inverse magnetic catalysis effect in magnetized QCD matter.
Using chiral perturbation theory, this study identifies and characterizes two distinct types of baryonic vortices in rotating nuclear matter, demonstrating that finite-size causality constraints regularize the energy divergence of global vortices, thereby establishing them as viable topological excitations that compete energetically with local vortices.
This paper proposes a flavor-deconstructed gauge theory where embedding the Standard Model in separate gauge groups for each fermion family naturally yields sequential dominance, offering a viable explanation for the flavor structure of both neutrinos and charged leptons.
This paper presents the derivation of two-loop leading-colour scattering amplitudes for bottom-quark pair production in association with a Higgs boson () at the LHC, focusing on top-Yukawa contributions within the massless bottom and heavy-top approximations, and expresses the finite remainder using one-mass pentagon functions with analytically reconstructed rational coefficients.
This paper utilizes Born-Oppenheimer Effective Field Theory and lattice QCD calculations to demonstrate that the near-degeneracy and specific decay patterns of the hidden-bottom tetraquarks and arise from the degeneracy of their underlying light degrees of freedom, identified as and adjoint mesons.
This paper investigates the thermal static potential in (2+1)-flavor QCD at finite density using a Taylor expansion, revealing an enhancement of in-medium screening in both real and imaginary parts that offers new constraints on heavy-quark interactions relevant to the RHIC Beam Energy Scan and future FAIR experiments.
This paper investigates whether a chiral density wave phase at large baryon chemical potential can enable QCD-induced little inflation to produce observable nano-Hz gravitational waves, but concludes that the resulting latent heat is insufficient to support a viable cosmological scenario.
Using CLS lattice ensembles with a refined analysis strategy involving telescopic series and new kernel functions, this paper presents an updated, high-precision ab initio determination of the hadronic vacuum polarization contribution to the running of the electromagnetic coupling and the electroweak mixing angle, aiming to meet the projected precision requirements of future electroweak measurements at next-generation colliders.
This paper demonstrates that a unitarity-conserving Peccei-Quinn inflation model, unlike its conventional counterpart, achieves better agreement with ACT observational data on the scalar spectral index and permits significantly larger axion decay constants ( GeV) without requiring unnaturally small self-couplings, thereby allowing to exceed the standard cosmological symmetry restoration bound.
This paper investigates two distinct single-field brane inflation scenarios—radial and angular—within a warped deformed conifold geometry, where moduli stabilization via D7-brane Kuperstein embeddings generates the inflaton potentials, demonstrating that embedding these models in the warm inflation paradigm with dissipation enables them to satisfy current observational constraints from Planck and ACT, whereas their cold inflation counterparts fail.
