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.
At Gist.Science, we process every new preprint in this category as soon as it appears on arXiv. We strip away the dense jargon to offer both accessible plain-language explanations and detailed technical summaries, ensuring that groundbreaking research is understandable to everyone from students to seasoned experts. Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This paper proposes a framework where Yukawa hierarchies emerge from powers of anarchic spurions in higher $SU(2)$ and $SU(3)$ flavor representations via progressive rank lifting, offering testable predictions for flavor-changing neutral currents and stochastic gravitational-wave backgrounds.
This paper demonstrates that in real 3-Higgs-doublet models with spontaneous CP violation and softly broken discrete symmetries, perturbativity constraints on quartic couplings prevent new scalar masses from significantly exceeding the electroweak scale, even when arbitrary large mass terms are present, a finding supported by both analytic and numerical analyses of the scalar sector's phenomenological consequences.
This paper proposes a theoretically clean and experimentally simple "one-point charge-correlator" probe for measuring the Sivers effect in back-to-back deep-inelastic scattering using only charged track signs and directions, which achieves factorization without relying on non-perturbative fragmentation functions and provides high-precision resummed predictions for future Electron-Ion Collider experiments.
This paper investigates the discovery potential of doubly-charged bileptons at the High-Luminosity LHC through direct pair production and heavy-quark-mediated channels, demonstrating that the latter offers significantly enhanced sensitivity capable of achieving a discovery for heavy quark masses up to 2.5 TeV and bilepton masses up to 2 TeV due to a distinctive, background-free four-lepton signature.
This paper proposes that accretion-induced collapses of rapidly-rotating, highly magnetized white dwarfs can generate magnetically-dominated relativistic outflows capable of accelerating heavy nuclei to ultra-high energies, potentially accounting for the observed flux of ultra-high-energy cosmic rays.
This paper utilizes the MC-CGC event generator to demonstrate that LHCb data favors HERA-constrained initial conditions for the rcBK evolution equation and that the dense-dense factorization framework better describes mid-rapidity particle production than the dilute-dense DHJ approach, while also providing predictions for future ALICE FoCal measurements.
This paper proposes that in a left-right weak interaction model, baryon and lepton asymmetries arise during the hadronization of quark-gluon plasma due to CP-violating differences in neutron and antineutron lifetimes caused by right-handed vector boson mixing, while sterile neutrinos account for dark matter and carry a compensating lepton asymmetry.
This paper investigates how accretion on primordial black holes (PBHs) prolongs early matter domination and shifts Big Bang nucleosynthesis constraints on PBH reheating scenarios—derived from isocurvature-induced gravitational waves and merger limits—towards smaller formation masses and initial abundances, with gravitational wave constraints proving more stringent than merger constraints.
This paper demonstrates that for a CFT on a flat open solid torus, the two-point function and disjoint entanglement entropy are exactly paired with finite bulk geodesics and entanglement wedge cross-sections, respectively, without requiring large , strong coupling, or heavy operators, thereby revealing a broader exact-pair structure in AdS/CFT beyond standard singular limits.
This paper investigates front propagation in an inhomogeneous model, demonstrating that while standard kink-based effective descriptions work well, a modified effective model is required to accurately capture the dynamics of half-kinks representing the decay of unstable states.
