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 fits and the 95 GeV diphoton excesses in the Supersymmetric Georgi-Machacek Model

This paper demonstrates that the Supersymmetric Georgi-Machacek model can explain the 95 GeV diphoton excesses observed by ATLAS and CMS through a light custodial singlet Higgs boson, but fails to simultaneously account for the LEP bbˉb\bar{b} excess due to its highly constrained Higgs potential, which also yields sharp predictions for the remaining mass spectrum and offers distinct signatures to differentiate it from the non-supersymmetric GM model at future colliders.

Neutrino masses, matter-antimatter asymmetry, dark matter, and supermassive black hole formation explained with Majorons

This paper proposes a singlet Majoron model with an enhanced electromagnetic anomaly that simultaneously explains neutrino masses, the baryon asymmetry of the Universe, dark matter, and the formation of high-redshift supermassive black holes through the decay of eV-scale Majorons into photons.

Convergence in charmonium structure: light-front wave functions from basis light-front quantization and Dyson-Schwinger equations

This paper demonstrates a remarkable convergence between Basis Light-Front Quantization and Dyson-Schwinger equations in predicting charmonium light-front wave functions and associated observables, thereby validating both Hamiltonian and Lagrangian approaches for studying non-perturbative QCD structure.

Axionlike particle-assisted supercooling chiral phase transition in QCD: Identifying Coleman-Weinberg type-chiral phase transition in QCD-like scenarios

This paper proposes a new QCD thermal history scenario where a heavy axionlike particle with a mass of approximately 5 MeV induces a Coleman-Weinberg type chiral phase transition via supercooling, potentially leading to unique cosmological phenomena such as mini-inflation, nonperturbative reheating, and the production of gravitational waves and primordial black holes.

Accessing baryon-antibaryon generalized distribution amplitudes in e±γ→e±BBˉe^{\pm} γ\to e^{\pm} B \bar{B}

This paper investigates the feasibility of extracting baryon-antibaryon generalized distribution amplitudes from the e±γ→e±BBˉe^\pm \gamma \to e^\pm B \bar{B} process using QCD factorization and numerical estimates, demonstrating that such a measurement is achievable at the Belle II experiment.

Further Reduction of the PDF Uncertainty in the High-Mass Drell-Yan Spectrum Utilizing Neutral and Charged Current Inputs

This paper updates a previously proposed strategy by incorporating charged current Drell-Yan final states alongside neutral current inputs to significantly reduce Parton Distribution Function uncertainties in high-mass Drell-Yan spectra, thereby enhancing the sensitivity of Beyond the Standard Model searches at the LHC.

Three-body resonances of ααMααM clusters (M=ϕM=ϕ, J/ψJ/ψ, ηcη_c) in M8Be^{8}_{M}{\mathrm{Be}} nuclei

This study investigates the structural effects of ϕ\phi, J/ψJ/\psi, and ηc\eta_c mesons on 8^8Be nuclei using HAL QCD potentials and the Gaussian expansion method, revealing that the ϕ\phi meson strongly binds the system into stable states while J/ψJ/\psi and ηc\eta_c interactions are weaker and form only shallow bound states, with specific predictions for new α\alpha-charmonium bound states and the non-Borromean nature of J/ψ8Be^{8}_{J/\psi}\text{Be}.
