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 the KM3NeT neutrino detector, specifically its ORCA component, can serve as a powerful Earth-scale search for long-lived dark particles produced in rare meson decays at the LHC, offering competitive sensitivity to existing limits without requiring new dedicated detectors.
This paper proposes that in supersymmetric models with discrete R-symmetries and R-parity violation, the decay of thermally produced WIMPs before Big Bang Nucleosynthesis can alleviate the cosmological moduli problem by suppressing WIMP overproduction, thereby allowing for lighter moduli masses (~130 TeV) that reconcile naturalness with stringy moduli, despite potential complications from long-lived particle cascade decays.
This paper systematically investigates baryon-baryon interactions in singly bottomed dibaryon systems using the chiral quark model, revealing that low-isospin and decuplet-decuplet channels favor stronger attraction and identifying numerous potential bound states that warrant further experimental verification.
This paper proposes that measuring the flavor ratio of displaced leptons from long-lived charged mediators at the High-Luminosity LHC provides a unique, -independent method to determine the neutrino mass ordering, as the "shared-coupling condition" in various neutrino mass models predicts a distinct electron-to-muon yield ratio that differs by over an order of magnitude between the Normal and Inverted Hierarchies.
This paper reviews the MAP Collaboration's next-to-next-to-leading order extraction of unpolarized di-hadron fragmentation functions using BELLE data with neural networks and flavor decomposition, while also presenting a revised next-to-leading order calculation for transversely polarized di-hadron fragmentation functions that corrects previous literature results.
This paper demonstrates that while hadronization significantly dilutes conventional parton-level signatures of gluon saturation at the EIC, the global hadronic recoil remains a robust and accessible observable for probing the underlying broadening through Bayesian unfolding.
This paper proposes that the high-energy nuclear recoil observed by the LUX-ZEPLIN experiment can be explained by exothermic dark matter with a mass of 30–200 GeV and a mass splitting of 0.5–1 MeV within a minimal inelastic dark photon model, a scenario that is consistent with various cosmological histories and predicts observable events in argon and germanium detectors.
This paper establishes next-to-leading order unitarity bounds and bounded-from-below conditions for the Georgi-Machacek and extended Georgi-Machacek models, using these improved theoretical constraints to perform global fits with LHC Higgs data that disfavor specific coupling regions and set upper limits on scalar quartic couplings and heavy Higgs mass differences.
This paper demonstrates that chaotic inflation driven by potentials can be reconciled with recent ACT data and remain consistent with effective field theory constraints within the Palatini formulation of gravity by employing a specific non-minimal coupling to gravity and kinetic mixing, while also showing the model's embeddability in supergravity.
This paper examines the viability of bi-large neutrino mixing patterns by confronting them with the first results from the Jiangmen Underground Neutrino Observatory (JUNO), assessing their ability to discriminate among models, predicting specific octant and CP properties, and discussing the implications for neutrinoless double beta decay.
