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 demonstrates that weak lensing analysis of future LSST data can provide competitive and complementary constraints on primordial non-Gaussianity models, particularly those with features on small scales, by resolving their signatures in the deeply nonlinear late-time density field through a suite of over thirty templates and new simulations of resonant signatures.
Motivated by LHCb observations, this study employs the perturbative QCD factorization framework to analyze decays into axial-vector and tensor mesons, predicting branching ratios within experimental reach and establishing the dominance of longitudinal polarization amplitudes.
This paper presents updated running quark and lepton Yukawa couplings and mixing parameters across various energy scales within the Standard Model and MSSM frameworks, leveraging the reduced uncertainties in the 2024 Particle Data Group fermion mass determinations to assess their impact on theories beyond the Standard Model.
This paper proposes a protocol for enhancing dark matter detection sensitivity by projecting quantum sensors into a collective excited state, which suppresses non-collective noise by a factor equal to the number of sensors without requiring the maintenance of entanglement during signal accumulation.
This paper presents the first constraints on the axion-photon coupling () using soft X-ray observations of the quiet Sun from India's Chandrayaan-2 mission, establishing an upper limit of approximately GeV at 95% confidence for axion masses below eV.
This paper demonstrates that core-collapsed self-interacting dark matter halos of approximately provide a unified explanation for three distinct astrophysical observations: the dense perturber affecting the GD-1 stellar stream, the structural properties of a perturber in the JVAS B1938+666 strong lensing system, and the origin of the Fornax 6 stellar cluster.
This paper presents the first lattice QCD determination of the electromagnetic form factors for the tetraquark, revealing its internal structure as a compact bound state of a heavy diquark and a light antidiquark with a charge radius significantly smaller than that of the threshold.
This paper demonstrates that the Next-to-Two-Higgs-Doublet Model (N2HDM) can simultaneously explain the LHC and LEP anomalies at 95 GeV and the 650 GeV excess by predicting a heavy CP-even Higgs boson decaying into a 125 GeV Higgs and a 95 GeV scalar, a scenario consistent with current experimental constraints and offering distinct testable signatures for future collider runs.
Using three-point QCD sum rules with vacuum condensates up to dimension 5, this study investigates the strong decays of four vector tetraquark candidates for the and finds that the predicted total width of for the configuration () aligns excellently with experimental data, thereby supporting this specific tetraquark interpretation.
This paper employs QCD sum rules to construct color five-quark currents and calculate the mass spectrum of hidden-charm doubly-strange pentaquark states with specific quantum numbers, providing theoretical predictions for future experimental searches in decays while challenging the conventional "good" and "bad" diquark classification.
