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.

This paper presents a renormalon-subtracted potential nonrelativistic QCD framework that combines variational and Green's function Monte Carlo methods with NNLO potentials to predict the masses of fully-heavy baryons and the binding properties of fully-heavy tetraquarks, achieving improved perturbative stability while identifying discrepancies with lattice QCD that are consistent with neglected corrections.
This paper introduces the "Seesaw Reheating" scenario, where an inflaton transfers energy to a long-lived intermediate scalar associated with lepton number breaking, thereby linking the reheating temperature to neutrino mass generation and sterile-neutrino dark matter through a distinct thermal history characterized by relativistic time dilation and a relativistic-to-non-relativistic transition.
This paper reports progress toward calculating mixed QCDxEW corrections for charged-current Drell-Yan processes with leptonic decay at high transverse masses using the Nested Soft-Collinear Subtraction framework, presenting NNLO real corrections and comparing their impact with neutral-current channels to meet future LHC precision requirements.
This paper calculates tensor-polarized parton distribution functions for the deuteron using a convolution model, revealing significant discrepancies with existing HERMES data that suggest the need for new theoretical mechanisms beyond a simple proton-neutron bound system, while providing predictions for upcoming experimental tests at Jefferson Lab and Fermilab.
This paper proposes that accelerator neutrino experiments, specifically SBND and DUNE, can serve as terrestrial probes for in-medium hyperon potentials by analyzing charged-current interactions that produce and hyperons inside nuclei, with the StrangeMC simulation forecasting a precision of approximately 6 MeV for the potential () and highlighting the role of hyperon-nucleon cross sections in constraining the potential ().
This paper demonstrates that charged-current neutrino interactions on argon at facilities like DUNE and SBND can constrain in-medium hyperon potentials through final-state interaction observables, thereby providing critical inputs to resolve the hyperon puzzle in neutron star equations of state.
This paper demonstrates that quarkyonic matter, when dressed with in-medium hyperon potentials constrained by hypernuclear and neutrino data, statistically resolves the neutron-star hyperon puzzle by delaying the onset of charged hyperons and suppressing core strangeness, thereby allowing for hyperon-free stars while predicting a significantly reduced sensitivity of the maximum mass to hyperon potentials compared to mean-field models.
This paper investigates how the running of the QCD coupling affects anti-collinear resummation in JIMWLK evolution, deriving a resummed BFKL kernel that reveals a significant reduction in the Pomeron intercept due to combined resummation and coupling effects, despite a surprising cancellation that leaves the characteristic function at unchanged.
This paper investigates the potential to discover new invisible particles at the LHC by analyzing semi-visible Higgs decays ( and ) using an effective field theory framework, demonstrating that despite large backgrounds, signal extraction is feasible through both cut-based and multivariate BDT analyses.
Using QCD sum rules, this paper predicts the mass and decay width of the fully-beauty tensor tetraquark , concluding that while it is stable against strong decays into heavy meson pairs, it transforms into conventional particles via annihilation with a calculated width of MeV.
