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 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 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 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.
This paper presents the first complete next-to-leading order QCD calculation for fully charm tetraquark production at hadronic collisions, incorporating gluon radiation effects through resummation and utilizing LHCb and CMS data to extract universal long-distance matrix elements and predict kinematic distributions for the and its spin-zero partners.
This paper presents the first example of a nonlocal, Lorentz-invariant quantum field theory that simultaneously satisfies renormalizability, unitarity, and causality while violating CPT symmetry, offering a viable framework for explaining the universe's baryon asymmetry.
This paper employs next-to-leading order QCD sum rules to analyze light tetraquark states, concluding that the is unlikely to be a tetraquark while identifying the as a strong tetraquark candidate around 2.0 GeV and suggesting the is less likely to be a tetraquark than previously thought.
This paper employs Bayesian inference within a unified framework to constrain the neutron star equation of state across hadronic, crossover, and quark phases, revealing that current multi-messenger data strongly limit low-to-intermediate density nuclear symmetry energy parameters while leaving high-density quark matter properties largely unconstrained until next-generation observations become available.
