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 an updated analysis of the long-standing puzzle by incorporating recent Belle II measurements of CP asymmetries in the decay, offering new insights into potential sources of CP violation beyond the Standard Model.
This paper argues against the proposal to rename "neutrinoless double beta decay" as "Majorana double beta decay," asserting that the current terminology is more accurate and that the motivations for the change lack credibility.
This paper proposes a measurement program at the Electron-Ion Collider using polarized electron scattering on deuteron and He to directly constrain the axial two-body current and resolve current discrepancies in meson-exchange current models, which are critical for reducing uncertainties in long-baseline neutrino oscillation experiments.
This paper argues that the observed sequential suppression of and states in high-multiplicity $pp$ collisions cannot be explained by standard hadronic or string-based models, but instead provides compelling evidence for the formation of an early, globally correlated partonic medium.
This paper utilizes the two-flavor Nambu-Jona-Lasinio model to demonstrate that soft mode dynamics near the QCD critical point and two-flavor color superconductivity critical point induce a pseudogap in quark spectra and significantly enhance electric conductivity and dilepton production rates, offering potential signatures for detection in relativistic heavy-ion collisions.
This paper investigates the decay within an effective-Lagrangian framework incorporating a constant on-shell Omnès factor to model leading rescattering, achieving a theoretical width close to experimental values while highlighting the need for a fully -dependent dispersive analysis to resolve remaining discrepancies in Dalitz plot projections.
This paper demonstrates that paleo-detectors using olivine targets can achieve unprecedented sensitivity to sub-GeV dark matter accelerated by cosmic rays and supernovae, enabling the detection of nuclear recoil tracks over geological timescales and probing parameter regions inaccessible to current and near-future experiments.
This paper proposes a Type-I seesaw model with non-holomorphic modular symmetry that successfully accommodates normal hierarchy neutrino data with a of 7.06 and predicts specific constraints on mixing angles and CP violation, while ruling out the inverted hierarchy scenario.
Using a constituent quark model and diffusion Monte Carlo method, this study compares fully antisymmetric sexaquarks and baryon-baryon-like dibaryons in the $uuddss$ system, finding that only the latter configuration yields loosely bound states near the two-baryon threshold while all other structures remain compact.
This paper challenges the recent MAMI collaboration's determination of the hypertriton binding energy by proposing that the observed sharp pion-momentum line instead originates from the weak decay of the ground state of hyperhelium-7 into lithium-7.
