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 investigates the sensitivity of various proposed remote LHC detectors to light long-lived neutralinos decaying into a photon and neutrino in R-parity violating supersymmetric models, finding that the ANUBIS detector offers the best projected sensitivity among the considered experiments.
This paper proposes that the trapped misalignment mechanism for axion-like particles can simultaneously generate observable gravitational waves and strong, helical intergalactic magnetic fields, thereby linking dark matter candidates to multiple cosmological signatures detectable by upcoming observations.
Using QCD sum rules, this study predicts the existence of hidden-heavy tetraquark states with exotic quantum numbers in color-octet configurations, estimating their masses to be approximately 10.8–11.1 GeV for the bottom sector and 4.3–4.6 GeV for the charm sector, thereby offering theoretical guidance for future experimental searches at Belle II, LHCb, and BESIII.
This paper demonstrates that mixed QCD-QED contributions from gluon-photon initial states significantly enhance the pair production of highly charged leptoquarks by up to 33%, thereby strengthening mass exclusion limits derived from LHC data and establishing a new precision standard for bounding such states.
This paper predicts that sequential hadronization, where mesons form later than mesons, reproduces the observed elliptic-flow splitting in O--O collisions at TeV and establishes this splitting as a universal chronometer for the quark-gluon plasma's hadronization timeline.
The paper proposes an exact, finite kinematic sector of holography defined on a CFT over an open solid torus in the Weyl frame, which establishes bulk-boundary pairs without requiring standard approximations like large- or strong coupling and provides a replica-free definition of entanglement entropy.
This paper proposes a data-driven strategy to predict decays by explicitly incorporating hadronic resonance contributions, such as those from , rather than avoiding them, thereby enabling the use of hadron-collider data and enhancing sensitivity to large New Physics effects across the full kinematic spectrum.
This paper demonstrates that tracking experiments can effectively discriminate between different neutrinoless double-beta decay exchange mechanisms with high statistical significance using only a few well-reconstructed events, even in the presence of realistic reconstruction uncertainties, thereby validating the continued pursuit of tracking detectors for discovery-class experiments.
This paper demonstrates that standalone relativistic hydrodynamic effective field theories are inherently acausal and necessitates the inclusion of transient ultraviolet modes to restore causality while preserving the correct late-time hydrodynamic behavior.
This paper demonstrates that right-handed neutrino loops, interacting with the inflaton via a dimension-5 operator that induces an effective chemical potential, can significantly enhance cosmological collider signatures by softening heavy-mass suppression and amplifying oscillatory non-Gaussianities in the primordial three-point correlator.
