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 utilizes QCD sum rules to calculate the ground state masses of pentaquark candidates with specific quantum numbers and proposes searching for them in the mass spectrum via the exclusive decay to distinguish their diquark-diquark-antiquark structure from molecular configurations.
This paper demonstrates that in scalar field theories with degenerate vacua, the vacuum-dependent scalar field mass induces an anisotropic emission of radiation from domain walls, creating a "rocket effect" that biases their evolution toward the lower-mass vacuum and accelerates network decay, a mechanism distinct from and more dominant than potential barrier asymmetries.
This paper presents three NLO+PS generators that incorporate all-order threshold-enhanced QCD corrections to analyze non-relativistic effects, toponium contributions, and finite-width impacts on top-antitop pair production near threshold at the LHC, addressing recent experimental observations by ATLAS and CMS.
This paper presents the first next-to-leading order calculation of and transition form factors using soft-collinear effective theory light-cone sum rules, deriving factorization formulae, isolating excited states from ground-state contamination, and providing phenomenological predictions for branching fractions and lepton flavor universality ratios.
This paper proposes a novel method that leverages phase information from multiple nanohertz continuous gravitational wave sources to infer pulsar distances in two dimensions, demonstrating through simulations that this approach can achieve sub-parsec precision and significantly improve host-galaxy identification for gravitational wave sources.
This paper demonstrates that dilaton effective field theory serves as a diagnostic tool to distinguish between near-conformal confining and infrared conformal gauge theories, successfully classifying the theory with fundamental fermions as confining and the theory with adjoint fermion as infrared conformal through the analysis of lattice data.
This paper presents the first search for primordial non-Gaussianity signals mediated by Kaluza-Klein gravitons and radions using Planck 2018 data, finding no significant evidence for such effects while identifying a 5D model capable of generating detectable signals for future surveys.
This study investigates the possibility of antibottom-strange molecular pentaquarks near and thresholds using a one-boson-exchange model, predicting the existence of near-threshold bound or resonant states with masses between 6.44 and 6.52 GeV that primarily manifest as enhancements in the , , and invariant mass spectra.
This paper assesses the current observational status of single scalar field dark energy models, concluding that while they remain a viable and flexible framework, they are currently only marginally distinguishable from a cosmological constant due to fundamental observational limits and persistent underdetermination, necessitating improved low-redshift growth measurements and a deeper understanding of gravitational screening for future validation.
Using effective field theory, this paper factorizes elastic, single, and double diffractive $pp$ scattering in the Regge limit to demonstrate that while rapidity anomalous dimensions and Pomeron evolution are universal, the diffractive parton distribution functions differ between $ep$ and $pp$ processes, thereby establishing their non-universality in hadronic collisions.
