This paper proposes a unified framework where a dark Higgs field drives cosmic inflation and a dark photon serves as dark matter, demonstrating that a low-reheating scenario with significant entropy dilution allows for viable WIMP and FIMP candidates consistent with cosmological observations and potentially accessible to current and future experiments.
This paper proposes that a hypothetical color-octet, electroweak-singlet scalar particle () could explain a excess in CMS 4-jet data at a dijet mass of approximately 0.95 TeV, with a complex scalar variant providing a better fit to the observed signal shape and rate than a real scalar.
This paper proposes a radiative three-loop model utilizing vectorlike leptons and asymmetric Yukawa couplings between two scalar doublets to simultaneously generate neutrino masses, provide a dark matter candidate, and remain consistent with current experimental constraints on flavor violation and mixing data.
This paper investigates how the presence of primordial black holes significantly accelerates the decay of cosmic axion string loops through enhanced energy radiation, offering a potential observational signature for axion dark matter and cosmic strings.
Using an exact Andreev soft-wall holographic model, this study reveals that relativistic rotation exceeding 16% of the speed of light induces crossover phase transitions in low-density rotating QCD matter up to a critical baryon chemical potential of approximately 363.55 MeV, beyond which first-order transitions dominate.
This paper proposes a model- and process-independent On-Shell renormalization scheme that eliminates the need for mixing matrix counterterms by utilizing a basis-free approach formulated entirely through self-energies, demonstrating its consistency by computing 1-loop hadronic -boson decay widths in the Standard Model.
This paper resolves a historical discrepancy in the definition of electric susceptibility in hot QCD by utilizing an exact fermion propagator and improved perturbation theory to demonstrate that the disagreement stems from the choice of thermodynamic ensemble and infrared regularization, while also constructing the susceptibility within a hadron resonance gas model for the low-temperature regime.
This paper presents a systematic NRQCD-based study of meson photoproduction at electron-proton colliders, revealing that while the direct channel dominates, the resolved contribution provides a significant correction in the low- region and grows with collision energy.
This study assesses the validity of the Born-Oppenheimer approximation in potential models for doubly heavy hadrons by benchmarking it against Gaussian expansion method results, revealing that while the approximation is accurate for lighter heavy-quark masses, its performance with different trial wave functions (Slater vs. Gaussian) diverges at higher masses due to the neglect of non-adiabatic corrections.
This paper presents a precision Standard Model analysis and new physics projections for the radiative decay at the LHC, demonstrating its potential to measure the branching ratio with sub-percentage accuracy and to probe axion-like particles and anomalous gauge bosons with enhanced sensitivity down to couplings of .
