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.

Using a unified Bayesian framework to analyze CMB, BAO, and supernova data, the study finds that updated processing and recent measurements largely resolve apparent tensions in the standard CDM model, concluding that claims necessitating a shift to evolving dark energy models are premature.
CoLLM is an AI engineering toolbox that leverages pretrained large language models and a graphical user interface to automate the generation of physically consistent event selection code and deep learning analyses, thereby lowering the programming and technical barriers for end-to-end collider analyses.
This paper investigates the canonical quantization of scalar and Maxwell fields in anti-de Sitter spacetime, establishing conditions for vacuum stability by demonstrating that a non-negative Hamiltonian can be achieved either through specific coupling constraints or by introducing ghost states with anti-commutation relations, while also confirming that the resulting renormalized energy-momentum tensors yield a stable, maximally symmetric vacuum.
This paper projects that the FCC-ee collider will achieve a precision of in measuring the CP-violating angle in Higgs-to-tau-tau decays at GeV, primarily through one-prong hadronic tau decays, while also deriving corresponding Effective Field Theory limits on CP-odd operators.
This paper demonstrates that primordial black holes catalyze the chiral phase transition by inducing a novel mixed-order phase structure near their event horizons and significantly enhancing the inverse duration parameter, thereby causing substantial shifts in the peak frequency and amplitude of the resulting stochastic gravitational-wave signals.
This paper proposes a clockwork mechanism to realize charged massive particles (CHAMPs) as dark matter without unnaturally small parameters, demonstrating that the model satisfies theoretical and experimental constraints while offering testable predictions for the LHC and future detection experiments.
This paper discusses the various roles of strong electromagnetic fields generated in relativistic heavy-ion collisions, highlighting the need for theoretical and experimental advancements to better understand quark-gluon plasma dynamics and ultraperipheral electromagnetic processes.
This paper investigates a fermionic dark matter candidate coupled to the Standard Model via electric and magnetic dipole operators mediated by a massive dark photon, finding that while cosmological observations already tightly constrain the parameter space—particularly for magnetic dipoles—future low-threshold semiconductor experiments offer crucial sensitivity to probe sub-10 MeV dark matter that remains viable against current direct detection limits.
This paper investigates the rare decay within both the Standard Model and a scalar leptoquark scenario, providing predictions for key observables in charmonium-free regions to guide future experimental searches for new physics at Belle II and LHCb.
This paper compares QCD+QED and QCD-only parton distribution functions (PDFs) across various global fitting groups, with a detailed focus on the NNPDF4.0 set, to analyze how peripheral effects influence the magnitude and shape of QED corrections as precision in proton structure studies increases.
