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 investigates the sensitivity of the proposed FCC-ee collider to axion-like particles (ALPs) coupling to electroweak gauge bosons across all planned center-of-mass energies, demonstrating that the facility can detect ALPs with couplings as low as a few via the three-photon final state and potentially probe their electroweak structure for masses below the Z-boson mass.
This paper proposes that the irreducible mass tail of primordial black hole formation, predicted by general relativity, smooths the reheating process and suppresses the associated gravitational wave signal, thereby reopening the possibility that the hot Big Bang originated from the evaporation of ultra-light primordial black holes.
This paper proposes that thermal relic dark matter can remain viable despite ultraweak couplings to the Standard Model by annihilating primarily into a hidden "darker" sector through strong hidden-concealed interactions, a mechanism demonstrated via coupled Boltzmann equations in two specific gauge models.
This paper proposes a method to extract short-distance information and resolve discrete ambiguities in the Standard Model prediction for by analyzing time-integrated and time-dependent CP asymmetries, demonstrating that an LHCb-like experiment could constrain the relevant short-distance amplitude to within 35% of its Standard Model value and resolve the ambiguity at over 3 significance.
This paper utilizes the Fisher matrix formalism to demonstrate that next-generation gravitational wave detectors, such as Cosmic Explorer and the Einstein Telescope, will be capable of distinguishing primordial black holes from exotic compact objects and neutron stars by detecting sub-solar masses out to redshifts of and tidal effects up to .
This paper proposes a first-principles framework using gradient flow and renormalization group transformations to analytically derive confinement in QCD, demonstrating that a scale-invariant gluon condensate drives the running coupling to an infrared fixed point consistent with infrared slavery.
This paper presents a comprehensive study of the Muonic Portal to Vector Dark Matter model, demonstrating its ability to simultaneously explain dark matter relic abundance and muon anomalies through a novel velocity-suppression mechanism while establishing stringent collider bounds on vector-like muon masses and predicting distinctive multi-lepton signatures for future searches.
This paper employs next-to-leading order QCD sum rules with covariant derivative currents and dimension-8 condensates to systematically calculate the masses of light excited mesons, successfully reproducing experimental data for various nonets and demonstrating the effectiveness of this approach for studying excited hadrons.
This paper proposes and validates an alternative method for reconstructing one-dimensional kinematic distributions from high-dimensional Monte Carlo simulations by approximating them with weighted sums of orthogonal basis functions, which yields smooth results, eliminates bin-to-bin fluctuations, and allows for optimized basis construction using leading-order perturbative information.
This paper evaluates the discovery potential of the tetraquark decaying into at LHCb, finding that a observation is feasible during Run 4 for optimistic production cross sections but would require the full Run 5 dataset for more realistic estimates, while remaining unobservable under conservative scenarios.
