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 paper proposes a Z3-symmetric extension of the Lorentz group to describe quark color triplets as entangled Lee-Wick fields with complex conjugate masses, resulting in sixth-order dispersion relations that naturally enforce the asymptotic confinement of colored quarks.
This paper employs the one-boson-exchange model to systematically investigate interactions between excited anticharm mesons and ground-state octet baryons, predicting a rich spectrum of loosely bound molecular pentaquark states with specific quantum numbers and mass ranges to guide future experimental searches.
This paper demonstrates that the background instability of quintessence models can be comprehensively understood through the lens of entropy by showing that a rapid increase in matter entropy, driven by the distance conjecture, violates the covariant entropy bound and implies the existence of a finite event horizon that conflicts with the trans-Planckian censorship bound, while also linking scale separation to the AdS distance conjecture.
Using the FAST telescope, researchers observed two X-ray dim isolated neutron stars to search for axion dark matter conversion lines, finding no significant signal but establishing the tightest upper limits on the axion-photon coupling constant for masses between 4.14 and 6.20 micro-eV.
This paper investigates determinations from exclusive decays by performing comprehensive fits with various form-factor parameterizations to compare their impact on the results and to assess the constraints on potential new-physics contributions using updated experimental and theoretical data.
This paper establishes a geometric framework for non-supersymmetric effective gauge theories by constructing supersymmetric embeddings of dimension-six operators and utilizing vector bundles to systematically organize gauge operators under field redefinitions, thereby revealing an underlying complex geometry.
This paper presents a general analytic framework that unifies freeze-in, ultra-relativistic freeze-out, and standard freeze-out mechanisms for dark matter production during non-instantaneous reheating, deriving critical temperature exponents and analytic relic yields that explain how varying reheating histories shift microscopic interactions between these distinct regimes.
This paper proposes a method to construct a realistic equation of state incorporating surface energy effects to study the QCD critical point, concluding that the extreme temperature precision required to observe critical exponents makes their experimental detection in heavy ion collisions unlikely, though signatures of a first-order phase transition may still be feasible.
This paper establishes that Casimir energies in nonlinear scalar and electromagnetic theories can be accurately computed using an effective-metric prescription derived from the Hessian of the Lagrangian or fluctuation branches, a method validated by exact agreement between direct mode summation and the effective-metric formula for nonlinear electrodynamics in a constant magnetic background.
This paper proposes that neutron stars undergoing a slow, strong first-order hadron-quark phase transition can resolve conflicting observational tensions regarding compact star masses and radii by supporting extended stable hybrid branches that simultaneously accommodate the high mass of GW190814's secondary component and the unusually small radii of HESS J1731--347 and XTE J1814--338.
