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 demonstrates that deep learning techniques combined with updated flux models can effectively discriminate semi-exclusive production from background, predicting a discovery significance for both photon- and pomeron-induced processes at the LHC with modest integrated luminosities.
This paper presents an improved determination of transition form factors using light-cone sum rules by incorporating one-loop radiative corrections to distribution amplitudes in the scheme and employing a daughter sum rule to simultaneously constrain Borel mass and threshold parameters, thereby identifying the dominant theoretical uncertainties and providing a framework for future refinements.
Using a novel simulation-based inference framework to overcome computational and statistical challenges, this study performs a joint analysis of MiniBooNE and MicroBooNE data within a 3+1 sterile neutrino model, revealing a significant tension () between the two experiments that reduces the overall preference for sterile neutrinos to .
This paper demonstrates that in a dark sector populated via freeze-in, the process of chemical equilibration can significantly enhance thermal corrections to the effective potential, potentially driving an inverse phase transition from a broken to a symmetric phase.
This paper employs the PACIAE model to simulate Au+Au collisions at GeV and applies the DCPC coalescence model to phenomenologically predict the production yields, transverse-momentum distributions, and rapidity spectra of axion-like particles (ALPs) formed from final-state photon pairs.
This paper calculates next-to-leading-order electroweak corrections to -boson pair production in photon-photon collisions at the LHC, revealing that while azimuthal lepton correlations remain perturbatively stable, specific correlation coefficients receive significant loop-induced shifts that establish a crucial Standard Model baseline for future precision tests of anomalous quartic gauge couplings.
This paper employs QCD sum rules based on three-point correlation functions to systematically calculate the transition form factors, semileptonic decay widths, and polarization observables for the decays of spin- bottom baryons (, , and ) into their spin- charmed partners, providing predictions that are compared with other theoretical results to aid in studying the properties of singly heavy baryons.
This paper analytically and numerically investigates how Earth's realistic density profile and a four-flavor (3+1) sterile neutrino framework with eV-scale mass splitting and non-standard neutral current interactions influence the systematic bias in reconstructing the CP-violating phase in long-baseline experiments, finding that while the bias remains negligible for baselines up to 5000 km, it grows for trajectories sampling the lower mantle and core due to a specific interference mechanism.
This paper investigates how ultralight dark matter in the de Broglie regime drives stellar oscillations through either stochastic excitation or resonant driving depending on coherence times, concluding that the resulting signals in solar and other stars are far too weak to be detected by current instruments.
This paper utilizes quantum simulation on an IBM quantum processor to demonstrate how visible neutrino decay modifies vacuum CP asymmetry in a scenario, successfully validating theoretical predictions for flavor probabilities and coherence while quantifying the significant contribution of daughter regeneration to the decay-induced shift.
