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 demonstrates that a nontrivial sound speed during inflation significantly alters the quantum-information diagnostics of cosmological perturbations by suppressing state purity, amplifying entropic and entanglement measures, and postponing the onset of classicality through modified decoherence dynamics.
This paper proposes a novel approach using quantum tomography to reconstruct the spin density matrix of diboson systems, enabling the simultaneous and superior constraint of both CP-even and CP-violating SMEFT operators by exploiting full Beyond-Standard-Model signatures, including pure quadratic new physics terms that are typically degenerate in traditional polarisation-blind observables.
This paper demonstrates that leveraging multidimensional correlations in baseline, recoil energy, and timing through both conventional likelihood analyses and machine learning techniques enables robust discrimination between sterile neutrino and non-standard interaction models in CENS experiments, even when total event rates are obscured by systematic uncertainties.
This paper investigates how the time-dependent chiral magnetic conductivity in quark-gluon plasma influences particle spectra and energy loss through chiral Cherenkov processes, revealing that these effects lead to strong jet polarization in relativistic heavy-ion collisions.
This paper demonstrates that heavy quark transport in weakly coupled non-Abelian plasmas is intrinsically non-Gaussian with asymmetric exponential tails beyond the leading logarithm, a robust feature shared with strongly coupled holographic plasmas that is essential for accurate equilibration dynamics.
This paper investigates the phenomenological prospects of the Two Higgs Doublet and Complex Singlet Scalar Extension (2HDMS) model as a dark matter candidate, demonstrating through benchmark scans and collider analyses that while the High Luminosity LHC may only offer hints of new physics, future lepton colliders serve as highly efficient discovery probes for this framework.
This paper interprets nine statistically significant LHC decay channels around 650 GeV as evidence for a sequence of spin-2 Kaluza-Klein graviton resonances (specifically T690) and potential spin-0 scalars within a composite or Randall-Sundrum framework, suggesting that these findings support the case for future high-luminosity colliders to produce and study these new particles.
This paper investigates whether supersymmetry can stabilize the mass of an ultralight dilatonic dark matter candidate against quantum corrections, concluding that while such a model can produce the observed dark matter abundance, irreducible gravitational supersymmetry-breaking effects render the dilaton's couplings to the Standard Model too weak for detection by current or proposed experiments.
This paper investigates how dark matter scatterings in intergalactic and galactic media attenuate and alter the flux, spectrum, and arrival directions of ultra-high-energy neutrinos, demonstrating that these effects can be used to constrain dark matter-neutrino interaction cross-sections even with unknown sources, as illustrated by the recent KM3230213A event.
This paper recasts existing analyses to search for charged Higgs bosons decaying via the $WZ$ channel, setting sub-permille limits on their production that constrain the triplet vacuum expectation value more stringently than previous modes or electroweak precision data, while a excess supports the existence of a GeV boson.
