Summary: This article focuses on cosmological particle production caused by a time-dependent scalar field and explores the mechanism of asymmetry production when the interaction explicitly violates symmetry and its motion is rapid enough to create particles. By combining the exact WKB analysis and the Landau-Zener transition, it is noted that perturbations before the non-perturbative analysis can greatly alter the structure of the theory's Stokes lines. The exact WKB analysis plays an important role in avoiding such discrepancies.

Summary: Studies have shown that the quantum effects of right-handed neutrinos in a gravitational background facilitate the leptogenesis mechanism, which can be probed complementarily by GW detectors and next-generation neutrinoless double beta decay experiments. Successful leptogenesis should correspond to specific plane limits, while recent pulsar timing data could be related to the results of 0νββ decay experiments.

Summary: The study focuses on the high scale leptogenesis with CP violation provided by the neutrino mixing matrix, investigating the transitions between different flavour regimes of baryon asymmetry generation in the Universe using Boltzmann equations. Particularly, it examines the behavior of eta(B) during the 1-to-2 flavour transition and determines the minimal scale and conditions for successful leptogenesis. The findings suggest that the considered scenarios are testable and falsifiable in low-energy neutrino experiments.

Summary: The proposed A(4) modular invariant flavor model of leptons breaks both CP and modular symmetries spontaneously through the vacuum expectation value of the modulus tau, predicting values for lepton mixing angles, masses, and the Dirac CP phase delta (CP). The modulus tau links the Dirac CP phase to the cosmological baryon asymmetry (BAU), with restrictions on the lightest right-handed neutrino mass and correlations between the predictive baryon asymmetry Y-B and the Dirac CP phase delta (CP).

Summary: This study extends a method for analyzing the sources of CP violation in baryogenesis models with quasi-degenerate neutrinos to the highly degenerate case. It is found that in general, the mixing and oscillation terms contribute with opposite signs to the generation of lepton asymmetry in the highly degenerate case, while the contribution of the interference term is typically very relevant and crucial. The expressions obtained are finite in the double degenerate limit of equal masses and couplings.

Summary: A statistically significant excess of gamma rays has been reported in the Galactic Center, which may be attributable to new physics. Majorana dark matter annihilating through a Higgs portal is considered as a candidate source for this signal, with a large CP-violation in the Higgs coupling potentially suppressing scattering rates. The exploration of two UV completions models help map out the available parameter space which can give a viable signal while respecting current experimental constraints.

Summary: The paper discusses non-equilibrium quantum transport equations for flavour-mixing fermions, deriving quantum kinetic equations that accommodate helicity and arbitrary mass differences in the context of resonant leptogenesis. The semiclassical Boltzmann limit of the equations is also derived, with an analysis on the accuracy of Boltzmann equations in different resonance conditions. The form of the CP-violating source is found to be crucial for the accuracy of the Boltzmann equations in certain cases.

Summary: The study explores the production of photons from coherently oscillating axionic fields in the presence of external electromagnetic fields, showing different behaviors of photon luminosity in relation to coupling parameter and configuration radius. A non-monotonic behavior of luminosity with coupling strength is observed in moderate to large coupling regimes, with a potential suppression at moderately large coupling and transition to exponential growth at sufficiently large coupling. Lattice simulations and discussions on medium effects and implications in astrophysical and cosmological settings are also conducted.

Summary: The Bogoliubov transformation in cosmological particle production can be explained by the Stokes phenomena and solved using special functions or the Exact WKB method. The study focuses on the effect of general interactions and classical scattering in cosmological particle production, as well as discussing the higher process of fermionic preheating using the Landau-Zener model.

Summary: This study examines the physics of inflation described through the dynamics of a scalar field and calculates the effective scalar field equations and corrected Friedmann equations to quadratic order. By estimating the magnitude of quantum corrections, the study investigates the impact of quantum corrections from different sources on inflation.

Summary: In this paper, the collider phenomenology and cosmology of the CP-even ALP are studied, and a certain production mechanism for the ALP is proposed. In an appropriate parameter region, the CP-even ALP can be produced from the decay of the Higgs boson and can lead to various signals, such as Higgs exotic decays and Higgs decay to displaced vertex plus missing energy. Furthermore, when the mass is light, the CP-even ALP can also serve as a candidate for dark matter, and there are methods to probe the dark matter using 21cm line measurement and other observations.

Summary: The Two Higgs Doublet Model predicts the emergence of 3 distinct domain wall solutions, we conducted numerical simulations and observed a local violation of the neutral vacuum condition on the domain walls. This violation is attributed to relative electroweak transformations across the domain walls.

Summary: Future gravitational wave observations are sensitive to the effects of SMEFT dimension-six operators on the Higgs potential, particularly when a first-order electroweak phase transition occurs. By performing a Fisher matrix analysis, the sensitivity of future gravitational wave observations to the wave function renormalization of the Higgs field and the SMEFT top-quark one-loop level effect is calculated. The effects of dimension-eight operators on the first-order electroweak phase transition are also discussed, and the sensitivities of future gravitational wave observations are compared with future collider experiments.

Summary: The study shows a connection between the parameters of transient CP violating phase in leptogenesis and the observation of electron electric dipole moment, with the left right symmetric supersymmetric model providing an effective method to connect these parameters. The research results indicate strict constraints on the scale of U(1)(B-L) symmetry breaking and the scale of SU(2)(R) symmetry breaking.

Summary: A simple and sensitive label-free electrochemical immunosensor for the detection of liver cancer biomarker AFP was constructed by modifying the electrode with N-doped hollow nanocarbon spheres decorated with gold nanoparticles. The optimized immunosensor showed a wide linearity and low detection limit for AFP analysis, and achieved satisfactory results in human serum.
