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 proposes that analyzing argon recoil data from the DEAP-3600 experiment can distinguish between two interpretations of the LZ 248 keV event: an excited pseudo-Dirac state, which predicts a detectable argon signal, and a ground-state Higgsino, which predicts no events due to kinematic thresholds.
This review synthesizes how neutron skins influence particle emission and collective dynamics across heavy-ion collision energies, linking these effects to the symmetry energy, nuclear structure, and astrophysical phenomena while outlining future experimental and theoretical pathways for constraining these fundamental properties.
This paper proposes that dark matter-induced neutron disappearance, where an incoming dark matter particle annihilates a bound neutron into an invisible scalar, offers a viable explanation for the high-energy nuclear recoil event observed by LUX-ZEPLIN without contradicting constraints from collider experiments or Borexino data.
This paper demonstrates that cosmological upper limits on the sum of neutrino masses remain robust against variations in neutrino abundance caused by post-decoupling photon injection or dark radiation, with such modifications shifting the 95% credible bounds by at most 0.004 eV and potentially worsening the tension between cosmological constraints and measured mass splittings.
This paper reviews recent findings on exotic heavy hadrons, demonstrating how short-range color correlations explain hidden-charm pentaquark patterns and predict hidden-bottom states, while also investigating the stability and decay dynamics of multihadron molecules like the bound state.
This essay argues that despite the 2012 discovery of the Higgs boson, particle physics is far from complete and instead faces an expansive agenda of inspiring questions and opportunities to deepen our understanding of the physical world.
This paper proposes that monitoring nearby galaxies for short gamma-ray bursts from supernovae, potentially triggered by deci-hertz gravitational-wave detections, could probe previously unexplored regions of axion-like particle parameter space by constraining the product of their nucleon and photon couplings to levels below the SN 1987A bound.
This paper presents the first computation of the six-loop Feynman diagrams required to determine the conservative gravitational interaction of two coalescing compact objects at the sixth post-Newtonian order within the effective field theory framework, providing the final missing ingredient for the complete description of their dynamics at this precision.
This paper introduces a metric-aware Deep Sets architecture that efficiently approximates the Energy Mover's Distance for collider events by enforcing key geometric constraints, achieving high accuracy and throughput while significantly reducing triangle inequality violations compared to unconstrained models.
This paper revisits precision muon decay within the Low-Energy Effective Field Theory (LEFT) framework to derive dependencies on dimension-five and -six operators, perform flavor-general fits to experimental data, and translate these constraints into the Standard Model Effective Field Theory (SMEFT) to limit specific single- and two-field new physics scenarios, ultimately finding that neutrino mass constraints from operator mixing are more restrictive than muon decay limits for lepton number violating cases.
