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.

Below are the latest papers in this dynamic field, ready for you to explore with clarity and depth.
This article reviews the fifty-year evolution of supersymmetry and supergravity from 1974 to 2024, highlighting their pivotal role in unifying fundamental interactions, their profound impact on cosmology and string theory, and the ongoing experimental efforts to validate these models.
This paper derives model-independent unitarity bounds on thermal dark matter mass in low-temperature reheating scenarios, demonstrating that while kination-like evolution tightens the limit to a few TeV, an early matter-dominated era allows dark matter to reach masses up to GeV due to significant entropy dilution.
This paper investigates the potential of the MAPP detector to discover sterile neutrinos via pair-production from and Standard Model bosons, demonstrating sensitivity to active-sterile mixing strengths as low as under specific coupling and mass conditions.
This paper advocates for analyzing flavor anomalies using a generic weak basis within the SMEFT framework, arguing that this approach eliminates unmeasurable assumptions about eigenstate alignment and enables the simultaneous explanation of anomalies and the extraction of transformation and Yukawa matrices through data fitting.
This paper utilizes state-of-the-art lattice calculations and experimental form factor data to visualize momentum flow and color-Lorentz forces within the nucleon, revealing that the gluon anomaly generates a critical attractive force on quarks comparable in strength to heavy-quark confinement.
This paper investigates the impact of strongly-interacting dark matter, modeled by a first-principles QCD-like gauge theory, on neutron star structure and confirms that such dark matter can be accommodated within current observational constraints.
This paper proposes a new mechanism where ultraviolet-dominated freeze-in scatterings involving heavy Majorana neutrinos simultaneously generate baryon and dark matter asymmetries, potentially explaining observed cosmic abundances through processes like dark wash-in and symmetric population depletion.
This paper identifies exact magnetic monopole solutions in spontaneously broken $SU(2)$ gauge theories within the BPS limit that possess a new internal degree of freedom, which modulates the monopole's energy density profile while preserving its total mass.
This paper challenges the interpretation of the nucleon's momentum current density as a continuous medium's pressure and shear forces, arguing instead that color interactions are long-ranged and that only the isotropic vacuum pressure term derived from the QCD trace anomaly effectively provides the confining potential for quarks.
This paper demonstrates that including twist-four kinematic power corrections modifies the subtracted constants in deeply virtual Compton scattering dispersion relations, causing the helicity-conserving amplitude to depend on double distributions in addition to the -term, a mixing effect that significantly impacts the extraction of pressure forces from Jefferson Lab data.
