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 by accounting for the competitive dynamics of dark matter evaporation and annihilation, solar observations can significantly constrain spin-dependent dark matter-nucleon scattering cross-sections for masses below the traditional 4 GeV evaporation limit, outperforming terrestrial direct detection constraints by up to five orders of magnitude.
This paper analyzes full Planck 2018 and BICEP/Keck 2018 CMB data to constrain stable cosmic string and domain wall networks, finding no statistically significant evidence for defects but observing a mild preference for non-zero cosmic string tension while significantly improving constraints and forecasting future sensitivities for upcoming experiments.
This paper proposes a lattice-ready entanglement observable, the vacuum-subtracted radius flow of Rényi entropy, to extract hadronic gravitational form factors by fitting flow data to a basis of spin-0 and spin-2 templates, thereby enabling the discrimination of scalar versus spin-2 entanglement control through the location and characteristics of the flow's extremum.
This paper presents a detailed analysis of Higgs boson production in association with a single top quark at 13 and 14 TeV, utilizing advanced modeling and kinematic optimization to constrain the top quark Yukawa coupling and project future sensitivities for the High-Luminosity LHC.
This paper presents a comprehensive reassessment of perturbative unitarity bounds in dimension-six SMEFT using spinor-helicity techniques, revealing that theoretical constraints on four-fermion operators often surpass experimental limits at TeV scales, particularly when enhanced by sum rules.
This white paper, produced by the EU-funded Cosmic WISPers network, reviews the theoretical motivations and ongoing searches for Weakly Interacting Slim Particles (WISPs) as dark matter candidates, while outlining a strategic roadmap to secure European leadership in this field through diverse and cost-effective experiments over the next decade.
This paper presents a complete and predictive set of thermal-relic targets for sub-GeV dark matter coupled to vector mediators in minimal anomaly-free U(1) extensions of the Standard Model, enabling robust discovery or falsification through electron recoil direct detection experiments.
This paper presents the first observational constraints on Luciano-Saridakis entropic cosmology using combined background data, demonstrating that the model provides a statistically robust fit to current observations and offers a viable extension to the standard CDM model with the potential to alleviate the Hubble tension.
This paper proposes a unified framework where a "flavor in ninths" structure arises from a discrete gauge symmetry that simultaneously explains quark and lepton hierarchies, stabilizes the QCD axion with and a specific ratio, and naturally solves the axion quality problem via high-dimensional operators, predicting a dark matter axion within the reach of near-term experiments.
This paper introduces a dual conformal invariance-preserving regularization method using dimensional and analytic techniques to drastically simplify the calculation of slightly off-shell dual conformal integrals, yielding compact logarithmic expressions in contrast to the complex polylogarithms produced by conventional dimensional regularization.
