This paper investigates CP violation in the decay within the two-Higgs-Doublet model by expressing amplitudes in physical couplings, confirming previous interference results while identifying additional CP-violating sources from internal bosonic and fermionic loop interferences that manifest as charge asymmetry in inclusive decays.
This paper presents a straightforward method for constructing the simplest Exotic Invariant, designated as E3.
This study investigates the macroscopic properties and universal relations of proto-neutron stars within Energy-Momentum Squared Gravity, revealing that while thermodynamic variables and the modified gravity parameter significantly alter individual stellar characteristics, the underlying correlations between these properties remain robust and largely unaffected.
This paper proposes a predictive supersymmetric framework where spontaneous breaking of the symmetry generates neutrino masses via a pseudo-Goldstone right-handed neutrino and a Majoron-like particle, successfully reproducing observed oscillation data while offering testable signatures in cosmology, neutrino decay, and future collider searches.
Using a decade of IceCube data, this study finds that while gamma-ray-bright blazars contribute minimally to the diffuse high-energy neutrino flux, X-ray-bright Seyfert galaxies—likely producing neutrinos in optically thick environments—could account for a significant portion, potentially up to the entirety, of the observed signal.
This paper investigates the Standard Model predictions for and decays by determining form factors from lattice QCD inputs and heavy-quark spin symmetry, subsequently calculating branching ratios, lepton-flavour-sensitive observables, and angular distributions for the cascade decay.
This paper presents the theoretical framework and detailed experimental design of the Muonium-to-Antimuonium Conversion Experiment (MACE), which aims to discover or constrain charged lepton flavor violation by searching for muonium-to-antimuonium conversion with a sensitivity of approximately .
This paper introduces SPARKX, an open-source Python package designed to streamline and enhance the analysis of relativistic kinematics in heavy-ion collision experiments by providing a comprehensive, multi-format toolkit that integrates with major simulation frameworks like SMASH and JETSCAPE.
This paper proposes a multicomponent supersymmetric dark matter model where the decay of a long-lived heavy fermion into a lighter boson at high redshifts generates an isotropic flux of ultra-high-energy neutrinos ( PeV) that explains the unassociated signal observed by KM3NeT.
Using the X-SCAPE event generator coupled with the SMASH afterburner, this study demonstrates that hadronic rescattering significantly modifies jet fragmentation observables even in small systems like collisions, highlighting the critical role of the hadronic phase in jet quenching across different collision environments.
