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 demonstrates that existing torsion balance experiments, originally designed to test the Equivalence Principle, already provide the most stringent constraints on sub-eV dark matter scattering with nucleons by leveraging coherence-enhanced signals from repeated interactions.
Motivated by the coincidences between dark matter and baryon energy densities, small-scale structure anomalies, and recent measurements, this paper investigates a GeV-scale chiral dark QCD model with a MeV-scale dark photon, identifying a finite, testable parameter space for future experiments like the Gamma Factory.
This paper investigates a scotogenic extension of the Standard Model with two inert doublets and three singlet Majorana fermions, identifying viable parameter spaces for radiative neutrino mass generation and dark matter while revealing that approximately 60% of these regions are excluded by recent CMS measurements of the boson mass due to constraints on the oblique parameter .
By re-analyzing data from the Taiwan Axion Search Experiment with Haloscope (TASEH) while accounting for scanning timing information, the authors derive world-leading constraints on dark photon dark matter that exceed naive rescaling limits by a factor of two and demonstrate the critical importance of avoiding magnetic-field-only vetoes to prevent discarding valid dark photon signals.
This simulation study of d-Au collisions at 200 GeV demonstrates that analyzing the skewness and kurtosis of two-particle cumulant distributions provides an effective method for distinguishing true elliptic flow from non-flow effects, as the former exhibits Gaussian-like characteristics while the latter shows significant deviations.
This paper presents a new formalism for estimating truncation errors in the electric basis of lattice gauge theory simulations on quantum computers, leveraging Hilbert space fragmentation to demonstrate that errors decay factorially with field truncation, thereby improving previous error estimates by a factor of up to for models like the Schwinger model and pure U(1) gauge theory.
Motivated by the Hubble tension, this study utilizes DESI DR2 and ACT DR6 data to constrain the varying electron mass and early dark energy models, finding a slight preference for a varying electron mass while ruling out significant early dark energy contributions, and subsequently identifying distinct inflationary scenarios favored by each model.
By fitting lattice data for nucleon and pion gravitational -form factors to a -meson pole and background term, the study demonstrates that the -meson acts as a dilaton consistent with effective theory predictions, thereby supporting the existence of an infrared fixed point in QCD and providing a physical interpretation of the -term.
This paper presents an Effective Field Theory study of the process at the Future Circular Collider (FCC-$hh$), demonstrating its unique capability to probe anomalous and couplings through a comprehensive collider analysis of the final state.
This paper proposes a TeV-scale baryogenesis scenario based on Dirac leptogenesis with resonantly enhanced CP asymmetry, which predicts observable decay asymmetries at colliders and a singlet scalar dark matter candidate consistent with thermal relic abundance.
