Bayesian analysis of the complex singlet model with phase transition gravitational waves

This paper demonstrates that the Taiji space-based gravitational-wave detector can effectively probe the complex singlet extension of the Standard Model by performing Bayesian and Fisher-matrix analyses to constrain Higgs self-couplings through the detection of electroweak phase transition signals, thereby highlighting the complementarity between gravitational-wave observations and collider physics.

Intrinsic Properties of Large CP Violation in the Complex Two-Higgs-Doublet Model

This paper investigates the parameter space for large CP violation in the complex two-Higgs-doublet model, revealing that Type-I scenarios predict eEDM values within next-generation experimental reach due to gauge-sector CPV, while Type-II models allow for nearly maximal Yukawa-sector CPV suppressed to negligible eEDM levels through destructive interference, alongside a newly identified "hidden CPV" phenomenon in the near-alignment limit that can be probed at future colliders.

Temperature-Dependent CPT Violation: Constraints from Big Bang Nucleosynthesis

This study utilizes Big Bang Nucleosynthesis abundances to constrain temperature-dependent CPT violation parametrized by an electron-positron mass asymmetry scaling as $T^2$ , establishing stringent limits on early-universe CPT violation that are inaccessible to zero-temperature laboratory experiments.

First mass determination of electroweak vortex rings in the Standard Model

This paper presents the first rigorous determination of the physical masses of electroweak vortex rings in the Standard Model, establishing values of 18.01 and 26.80 TeV for different winding numbers and revealing a self-stabilizing pinch mechanism driven by repulsive interactions and complex current distributions.

Confronting Vector-Like Quark Models with LHC Searches

This paper introduces VLQBounds, a public Python framework that automates the confrontation of Vector-Like Quark models with LHC exclusion limits by interpolating machine-readable experimental grids to provide rapid, channel-by-channel 95% confidence-level verdicts for various production and decay scenarios.

The Single Photon Signature of a Light Long-lived Neutralino at Remote Detectors at the LHC

This paper investigates the sensitivity of various proposed remote LHC detectors to light long-lived neutralinos decaying into a photon and neutrino in R-parity violating supersymmetric models, finding that the ANUBIS detector offers the best projected sensitivity among the considered experiments.

Audible Axion Magnetogenesis: Linking Intergalactic Magnetic Fields and Gravitational Waves

This paper proposes that the trapped misalignment mechanism for axion-like particles can simultaneously generate observable gravitational waves and strong, helical intergalactic magnetic fields, thereby linking dark matter candidates to multiple cosmological signatures detectable by upcoming observations.

Spectroscopy of hidden-heavy tetraquark states with $J^{PC}=0^{--}$ in a color-octet configuration

Using QCD sum rules, this study predicts the existence of hidden-heavy tetraquark states with exotic $J^{PC}=0^{--}$ quantum numbers in color-octet configurations, estimating their masses to be approximately 10.8–11.1 GeV for the bottom sector and 4.3–4.6 GeV for the charm sector, thereby offering theoretical guidance for future experimental searches at Belle II, LHCb, and BESIII.

Photon-initiated enhancements in the pair production of highly charged coloured particles

This paper demonstrates that mixed QCD-QED contributions from gluon-photon initial states significantly enhance the pair production of highly charged leptoquarks by up to 33%, thereby strengthening mass exclusion limits derived from LHC data and establishing a new precision standard for bounding such states.
