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.

Global $\Lambda$ hyperon polarization in low-energy heavy ion collisions -- a scenario without vorticity

This paper proposes that the global $\Lambda$ hyperon polarization observed in low-energy heavy-ion collisions can be partially explained (accounting for ~23% of the signal) by a mechanism linking it to long-standing transverse polarization phenomena via the alignment of production and reaction planes driven by directed flow, rather than solely by quark-gluon plasma vorticity.

Higher-order flow coefficients in dilepton emission from a magnetized hadronic medium

This study demonstrates that a strong magnetic field in hot hadronic matter induces significant higher-order azimuthal anisotropy in dilepton emission at low invariant masses, characterized by oscillatory flow coefficients ( $v_2, v_4, v_6$ ) driven by pion Landau-level quantization, thereby establishing dileptons as sensitive probes for constraining magnetic field strengths and hadronic dynamics in heavy-ion collisions.

A dual description of quarks and baryons: Quarkyonic matter within a relativistic quark model

This paper introduces the quarkyonic QMC (QQMC) model, which combines a dual quarkyonic picture with the quark-meson coupling framework to demonstrate that nuclear interactions significantly enhance the stiffening of the equation of state and trigger an earlier onset of quark saturation in dense matter compared to noninteracting models.

Analysis of Fully Heavy $P_{(3c2b)}$ and $P_{(3b2c)}$ Pentaquark Candidates

This paper employs the QCD sum rule approach with three distinct interpolating currents to predict the masses and current coupling constants of fully heavy pentaquark candidates containing three charm and two bottom quarks ( $3c2b$ ) or three bottom and two charm quarks ( $3b2c$ ) with spin-parity $J^P=\frac{1}{2}^{-}$ .

Exclusive $D \bar{D}$ pair production with low invariant mass in ultraperipheral Pb-Pb collisions at the LHC

This paper presents theoretical predictions for exclusive low-invariant-mass $D\bar{D}$ pair production in ultraperipheral Pb-Pb collisions at the LHC, incorporating continuum and resonant $\chi_{c0,2}(2P)$ contributions to calculate cross sections and differential distributions relevant for ALICE, ATLAS, CMS, and LHCb experiments.

Can QCD Axions Survive the Cosmological Constant Problem?

The paper demonstrates that vacuum-energy relaxation mechanisms, such as 'yoga' models, suppress the QCD axion's vacuum potential to the point where matter-induced effects dominate, altering its mass-coupling relation and driving it into an observationally excluded regime that renders conventional QCD axions non-viable.

Cogenesis of visible and dark matter in a scotogenic model

This paper proposes a scotogenic model where the CP-violating decay of a heavy right-handed neutrino simultaneously generates the visible matter asymmetry and a sub-GeV dark matter relic density via freeze-in, successfully reconciling these phenomena with neutrino parameters and flavor observables.

LHC Signatures of the Generic Georgi-Machacek Model

This paper proposes a generalized Georgi-Machacek Model without custodial symmetry to explain recent LHC excesses in vector-boson fusion channels by allowing mass splitting among new Higgs bosons, thereby accommodating observed signals in $W^\pm W^\pm$ , $WZ$, and di-photon production while satisfying experimental constraints.

F-Term Hybrid Inflation, Metastable Cosmic Strings and Low Reheating in View of ACT

This paper proposes a left-right unified F-term hybrid inflation model within a $U(1)_{\rm R}\times U(1)_{B-L}$ extension of the MSSM that successfully dilutes monopoles, generates metastable cosmic strings consistent with PTA gravitational wave observations and recent ACT data, and predicts a low reheating temperature below 34 GeV alongside a PeV-scale SUSY mass spectrum.

Doubly heavy spin- $\frac {3}{2}$ baryons spectrum in the ground and excited states

This study utilizes QCD sum rules with nonperturbative effects up to dimension ten to predict the masses and residues of ground and excited spin-3/2 doubly heavy baryons ( $\Xi^*$ and $\Omega^*$ containing $cc$, $bc$, or $bb$ quarks), providing essential theoretical guidance for future experimental searches.
