This paper investigates a parity-symmetric extension of the Standard Model that naturally explains small neutrino masses while allowing for substantial TeV-scale lepton number violation, demonstrating that a 10 TeV collider could probe boson masses up to 16 TeV through distinctive lepton number violating signals.
This paper utilizes finite-temperature QCD sum rules with updated quark masses and lattice-informed condensates to predict the thermal evolution of masses and decay constants for , , and mesons up to near-critical temperatures, revealing a suppression hierarchy consistent with binding energies and confirming the -- splitting observed by LHCb.
This paper investigates the minimal type II seesaw mechanism with two-zero neutrino mass textures, demonstrating how specific patterns of charged lepton flavor violation—particularly in tau decays—can be distinguished from other new physics scenarios and used to probe ultra-high flavor symmetry scales and doubly charged scalars at current and future experiments.
This paper proposes a machine-learning-based strategy that classifies neutrino interaction types prior to energy reconstruction to exploit intrinsic kinematic differences, thereby reducing modeling uncertainties and improving the accuracy and sensitivity of next-generation long-baseline oscillation experiments like DUNE by 10–20%.
This review paper examines hadron structure within the covariant Nambu-Jona-Lasinio model as a chiral effective theory of QCD, demonstrating its ability to replicate spontaneous chiral symmetry breaking and confinement while validating consistency with parton distribution functions and electromagnetic form factors against experimental data and future collider prospects.
This paper analyzes the vacuum structure of the Babu-Nandi-Tavartkiladze model, establishing theoretical constraints on scalar potentials and demonstrating that while simple mass inequalities guarantee global stability in specific limits, the general electroweak vacuum requires a case-by-case assessment due to the potential existence of deeper charge-breaking minima.
Using Einstein@Home computing resources to analyze LIGO data from observing runs O3a through O4a, this study conducts the most sensitive search to date for continuous gravitational waves from three central compact objects in supernova remnants, setting unprecedented constraints on their ellipticity and crustal anisotropy while identifying a single surviving candidate from G347.3-0.5 that warrants further investigation with upcoming data.
Using the perturbative QCD approach, this paper analyzes resonance contributions from and mesons and their excited states to the three-body decays , revealing that virtual contributions from the tails of and are comparable to those from higher resonances and thus constitute a significant component of these decays.
This paper presents the first constraints on sub-asteroid mass primordial black holes as dark matter using high-energy neutrino data from IceCube and ANTARES, establishing independent limits that future detectors like IceCube-Gen2 and KM3NeT could significantly improve.
This paper presents a comprehensive framework for modeling complex systems of oscillating and decaying neutrinos using open quantum system methods, specifically demonstrating that the Lindblad master equation, Liouvillian superoperator, and Kraus operators offer a fully general and numerically superior approach compared to traditional differential equation solutions.
