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.

Cogenesis of baryon and lepton number asymmetries matching the EMPRESS Data

This paper proposes a supersymmetric U(1)B−LU(1)_{B-L} extension of the Standard Model where the decay of a dominant B−LB-L Higgs field simultaneously generates the observed baryon asymmetry and a large electron neutrino asymmetry consistent with EMPRESS data through resonant leptogenesis, while also predicting a detectable gravitational wave background from cosmic strings.

UV Luminosity Functions from HST and JWST: A Possible Resolution to the High-Redshift Galaxy Abundance Puzzle and Implications for Cosmic Strings

This paper demonstrates that incorporating cosmic strings into galaxy formation models can explain the unexpectedly high abundance of bright high-redshift galaxies observed by JWST and HST without altering star-formation physics, while simultaneously establishing a new, tighter upper bound on cosmic string tension.

Constraining Gravitational Dark Matter with LHAASO and Fermi-LAT

This paper utilizes high-energy gamma-ray data from LHAASO and Fermi-LAT to constrain the mass and interaction strengths of four specific gravitationally produced decaying dark matter candidates, establishing stringent limits on their couplings to the visible sector and closing previously unconstrained parameter space for massive dark photons.

Towards the Direct Detection of Composite Ultraheavy Dark Matter in Quantum Sensor Arrays

This paper investigates the sensitivity of quantum sensor arrays to composite ultraheavy dark matter interacting via gravity and a Yukawa force, demonstrating through Monte Carlo analysis that future accelerometer arrays can distinguish between different density profiles and characterize the mass and size of such extended dark matter objects.

Electroweak right-handed neutrino portal dark matter

This paper proposes and analyzes a dark matter model where a fermion and a scalar interact with the Standard Model solely through electroweak-scale right-handed neutrinos in a Type-I seesaw framework, using Particle Swarm Optimization to identify viable parameter sets that reproduce the observed relic abundance via either secluded freeze-out or freeze-in while tightly linking neutrino physics, heavy neutral lepton phenomenology, and cosmological dark matter.

Residual Symmetries and Scalar Multiplet Vacuum Alignment in Non-Abelian Flavour Models

This paper establishes a one-to-one correspondence between broken residual symmetries and vacuum alignment corrections in non-Abelian flavour models, demonstrating how additional symmetry-breaking operators perturb special scalar orientations and providing a mechanism to identify and correct persistent phenomenological fine-tuning in models based on S4S_4, A4A_4, and Δ(27)\Delta(27) symmetries.

How large are curvature perturbations from slow first-order phase transitions? A gauge-invariant analysis

Using a gauge-invariant multi-fluid formalism to resolve ambiguities in conventional simulations, this paper demonstrates that super-horizon inhomogeneities from slow, strongly supercooled first-order phase transitions are unlikely to produce Primordial Black Holes, while providing a fitting formula for the resulting curvature perturbations and their associated observational constraints.

Gluon Generalized TMD signatures at the EIC from exclusive heavy (axial-)vector meson production

This paper proposes that exclusive heavy (axial-)vector meson production in lepton-proton collisions at the Electron-Ion Collider can serve as a unique experimental channel to probe the elusive gluon generalized transverse momentum-dependent distributions F1,4gF_{1,4}^g and G1,1gG_{1,1}^g through specific azimuthal-angle-dependent observables arising from virtual-photon polarization interference.
