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 identifies a viable light fermionic dark matter candidate with a mass between 58 and 63 GeV within the scotogenic inverse seesaw model that simultaneously explains neutrino masses and satisfies all current experimental constraints, while remaining testable by next-generation direct detection experiments and future colliders.
This paper explores the astrophysical implications of string-inspired multi-scalar-tensor theories by numerically solving the Tolman-Oppenheimer-Volkov equations to demonstrate how a screening mechanism can suppress the coupling of Brans-Dicke dilatons to macroscopic objects like neutron stars.
This paper proposes that the soft-breaking parameter in the Two-Higgs-Doublet Model acts as a distinct, non-electroweak source of mass for new scalars separate from the electroweak VEV, enabling the definition of mass fractions that are currently constrained by diphoton signal strength measurements and direct resonance searches.
This paper presents a new method for computing massless bosonic three-loop vacuum sum-integrals by generalizing tensor reduction via dimensionality shifts to finite temperature, thereby enabling the final evaluation of the NNLO Debye screening mass in hot QCD.
Using 16 years of INTEGRAL/SPI data to model detailed positron propagation and density variations, this study establishes the strongest constraints to date on sub-GeV dark matter annihilation and decay by analyzing the 511 keV emission profile, excluding cross-sections down to cm s for MeV-scale masses.
This paper derives analytic results for scalar massless bosonic vacuum sum-integrals at two loops by proving their factorization into one-loop structures, thereby enabling the elimination of these complex terms from perturbative expansions in hot QCD.
This paper proposes a direct search for QCD axion dark matter using superconducting transmon qubits as quantum sensors, demonstrating that combining cavity resonance with entangled quantum circuits can enhance the detection signal to reach the parameter regions predicted by QCD axion models.
This paper demonstrates that, contrary to the limitations observed in DC magnetometry, entangled GHZ states can enhance the sensitivity of AC magnetometry under parallel Markovian decoherence by scaling the interaction time as to mitigate noise effects and improve the detectable frequency bandwidth.
By extending the IdylliQ model of Quarkyonic matter to include strangeness, this study demonstrates that -quark saturation delays the onset of hyperons to higher densities (--) and suppresses their occupation, thereby mitigating the hyperon puzzle and preserving the stiffness of neutron star equations of state.
Using the topological-diagram approach within the framework, this paper investigates two-body decays into light scalar mesons and demonstrates that interpreting these mesons as tetraquark states provides a consistent explanation for experimental data, including the unexpectedly large branching fraction of , while predicting new decay rates that are accessible to current and future experiments.
