Summary: This paper investigates the gravitational production of dark photon dark matter during inflation when dark photons acquire mass through the Higgs mechanism. The research reveals that the energy density spectrum of dark photons can have two peaks at intermediate and small scales. Dark photons can explain dark matter, but their current mass needs to fall within a specific range.

Summary: Novel realizations of Higgs inflation within Supergravity are presented, largely related to the presence of a pole of order two in the kinetic term of the inflaton field. By adjusting the coefficients in the associated superpotential, inflationary observables can be made compatible with current data, and the scale M of gauge-symmetry breaking may lie within the MSSM range.

Summary: In this study, a scenario of spontaneous leptogenesis in Higgs inflation is proposed, with the assistance of two additional operators. These operators contribute to the generation of lepton asymmetry which eventually leads to baryon asymmetry in the universe, all during the rapidly changing Higgs field period. This scenario is compatible with the high reheating temperature of the Higgs inflation model.

Summary: Many minimal models of dark matter and canonical solutions to the hierarchy problem have been excluded or constrained by LHC and direct detection null results. The study introduces THPDM to generalize HPDM in Twin Higgs models and predicts a direct detection signal orders of magnitude below that of HPDM. Twin radiation contributions are suppressed in many Twin Higgs models, leading to possible signals at next generation experiments.

Summary: This work revisits the non-minimally coupled Higgs Inflation scenario and evaluates its observational viability. The study reveals discrepancies between the inflationary parameters and data from Baryon Acoustic Oscillation and type Ia Supernovae, but shows good agreement with the latest results from the CMS Collaboration on differential cross-section measurements of top quark production.

Summary: Research suggests that introducing an axion model in the Higgs field can solve the Li-7 puzzle in the early universe and reconcile the late-universe measurements. The model alleviates tensions between different data sets by suppressing the matter power spectrum with the axion's matter density.

Summary: The paper investigates how the Mirror Twin Higgs could be modified to be compatible with current cosmological constraints without explicit Z(2) breaking. It presents two simple models, one that can solve the N-eff problem and bring the abundance of mirror atoms to an allowed level, and another that leads to mirror neutron dark matter.

Summary: In this paper, the non-adiabatic evolution of dark sector is studied in the framework of a U(1)(L mu)-( L tau )circle times U(1)(x) extension of the standard model. The connection between the visible and dark sectors is established through a portal coupling. The temperature evolution and various non-equilibrium stages of the dark sector are analyzed. Constraints on the model parameters from laboratory and astrophysical searches are investigated. The parameter space for the non-adiabatic evolution of the dark sector is significantly constrained for certain values of mass and coupling, while other constraints depend on the mass ratio.

Summary: The lack of information before BBN allows for the presence of a new species 0 with a specific energy density redshift. This non-standard cosmological setup enables a larger coupling between the dark and visible sectors, even without thermal equilibrium. By considering the U(1)Lmu-LT 0 U(1)X gauge extension of the SM, different cosmological phases of the thermally decoupled dark sector are studied. It is shown that the dark matter relic density and muon (g - 2) anomaly can be reconciled within this scenario, satisfying various constraints.

Summary: The study investigates SU(2)_L x SU(2)_R x U(1)_(B-L) theories that incorporate the Higgs Parity mechanism, solving the strong CP problem and predicting three right-handed neutrinos. It introduces cosmologies where right-handed neutrinos are produced via different mechanisms and explores the parameter space where the lightest right-handed neutrino is dark matter and contributes to baryon asymmetry via leptogenesis. A theory of flavor is constructed to explain the lightness and stability of right-handed neutrino dark matter, while maintaining sufficient baryon asymmetry. The allowed parameter space can be probed by future colliders, lattice computations, and measurements of the neutrino mass hierarchy.

Summary: The recently suggested Festina-Lente (FL) bound provides a lower bound on the masses of U(1) charged particles in terms of the positive vacuum energy. The FL bound serves as a test for the consistent Higgs potential in the current dark energy-dominated universe and during inflation. The study reveals the implications of the FL bound on the UV behavior of the Higgs potential for a miniscule vacuum energy in the current universe.

Summary: The article investigates the general effective field theory describing the interactions of a massless dark photon with all Standard Model particles. The thermal production rate, cosmological yield, and contribution to the effective number of neutrinos of the dark photon are calculated. These predictions meet current observational bounds and will be tested in future measurements.

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: In this study, the baryon number abundance based on the charge transport scenario in the CP-violating two Higgs doublet model is evaluated. It is found that the observed baryon number can be reproduced in this model, with additional Higgs boson masses typically ranging from 300 to 400 GeV.

Summary: In this study, we investigate the ultraviolet behavior of Higgs inflation models above the apparent unitarity violation scale caused by the large non minimal coupling to gravity. By computing on-shell 4-point scattering amplitudes in the presence of a large inflaton background, we find that all tree-level amplitudes behave well at high energies below the inflaton background. This result holds true in both the metric and Palatini formulation, regardless of the frame used (Jordan or Einstein), and remains consistent even when an R-2 term is added to the action.

Summary: This paper studies the isocurvature modes of inflationary axions and explores how they can behave as isocurvature colliders. The authors provide an example where a boson intermediate particle can produce a clock signal in the squeezed limit, which could potentially be observed in future experiments.

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.
