Summary: Charged-current neutrino-nucleus scattering in the quasielastic region is investigated using the KIDS nuclear energy density functional. Uncertainties arising from the axial mass and in-medium effective mass of the nucleon are examined. By comparing with experimental data, constraints on the axial mass and effective mass compatible with the data are obtained. The total cross section is found to be insensitive to the effective mass, allowing for the determination of the axial mass independently of the effective mass uncertainty. Differential cross sections at different kinematics, however, are sensitive to both the effective mass and axial mass. Within the uncertainty range of the axial mass constrained by the total cross section, the dependence on the effective mass is examined. As a result, the axial mass and effective mass consistent with the experimental data are obtained.

Summary: FASER nu is expected to record the most energetic laboratory neutrinos ever studied, with the potential to observe neutrino neutral current scattering events. Researchers have demonstrated the use of deep neural networks to measure the neutral current scattering cross section, providing a complementary probe of neutrino nonstandard interactions to other tests such as oscillations and coherent neutrino-nucleus scattering.

Summary: Neutrino nonstandard interactions (NSI) can be constrained through coherent elastic neutrino-nucleus scattering, with a focus on charged current NSI and CP-violating phases associated with neutral current NSI. Limits on NSI parameters depend dramatically on the values of CP-phases, and COHERENT provides complementary constraints on explaining the discrepancy in the best-fit standard CP-phase obtained by T2K and NO nu A. The presence of additional NSI parameters may weaken the ruling out of the large mixing angle (LMA)-Dark-solution.

Summary: We simulate the Kelvin-Helmholtz cooling phase of proto-neutron stars using a new numerical code and the quasi-static approximation. By including charged-current neutrino-nucleon reactions and convective motions, we find that the inclusion of convective motion has the dominant effect on the cooling time-scale, neutrino signal, and composition of the neutrino-driven wind. The computation of nuclear correlations within the random phase approximation has a relatively small impact compared to the mean field approach.

Summary: In this study, the scattering of neutrinos on polarized and unpolarized free nucleons was examined, along with the polarization of recoil particles in these scatters. The parity-violating weak interaction leads to significant spin asymmetries, providing opportunities for future polarization measurements to access the proton axial structure and extract the pseudoscalar form factor from neutrino data without conventional assumptions. The pseudoscalar form factor can be determined through precise measurements with certain energy neutrinos, while the axial form factor can be extracted from scattering measurements using accelerator neutrinos of all energies.

Summary: A new physics scenario predicts the existence of an extra charged gauge boson, W', which induces non-standard neutrino interactions. The theoretical constraints on the simplified W' model and the CC NSI parameters are considered, and the expected constraints on the W' model at the LHC and HL LHC experiments are estimated using a Monte Carlo simulation. It is found that the interference effect plays a crucial role in constraining the non-standard neutrino interactions.

Summary: The study analyzes the production of eta mesons induced by charged current (anti)neutrinos through nonresonant and resonant diagrams using effective Lagrangians. A microscopic model based on SU(3) chiral Lagrangians is employed to determine the contribution from the nonresonant background terms while an effective phenomenological Lagrangian, with parameters obtained from experimental values, is used for the resonant diagrams. The model successfully reproduces experimental data for eta meson production, and predicts numerical values for various distributions and cross sections in the energy range up to 2 GeV. The results show that the S11(1535) resonance dominates the production of eta mesons induced by photons, electrons, neutrinos, and antineutrinos. The findings are relevant for current and future accelerator experiments as well as atmospheric neutrino experiments.

Summary: In this study, ab initio no-core shell-model (NCSM) calculations were performed for Ne18-24 isotopes using three realistic NN interactions. The results show that the INOY interaction performs better in terms of ground state binding energies, while all three interactions provide good agreement with the experimental low-energy spectra. Higher calculations are needed for long-range observables such as E2 transition strengths, electric quadrupole moments, and point-proton radii to obtain results comparable to the experimental data.

Summary: The role of pairing correlations for nucleon pairs with isospin T = 1 and T = 0 is investigated in ground-states of nuclei in the mass region 12 <= A <= 42. The analysis of two-nucleon densities resulting from nuclear shell-model calculations in one and two major shells is conducted, utilizing various tools including the sensitivity of correlation effects on components of the NN interaction. Significant effects on the resulting energies are observed due to the formation of T = 0 pairs. The robustness of T = 0 pairing explains why it does not lead to clear evidence in comparing energies of neighbored nuclei as the 'odd-even mass staggering' due to the formation of T = 1 pairing.

Summary: In this study, a comprehensive investigation of the sd-shell nuclei Si and P with varying neutron numbers from N=9 to N=20 was conducted using the microscopic effective valence shell interactions N3LO, JISP16, and DJ16A. These interactions, developed using ab initio no-core shell model wave functions and the Okubo-Lee-Suzuki transformation method, were compared to shell model calculations with the empirical USDB interaction. Energy spectra and electromagnetic properties were studied, and the theoretical results were compared to experimental data to assess the predictive power of the interactions. The DJ16A interaction reproduced the binding energies of the ground states most accurately, and a proton subshell closure at Z=14 was observed in Si. Additionally, the spin-tensor decomposition of the two-body interactions was presented to analyze the contributions from central, vector, and tensor components. Finally, spectroscopic strengths of the 23Al(d,n)24Si reaction were examined for a newly performed experiment at NSCL.

Summary: Potassium-40, a naturally occurring isotope, has significant implications for rare-event searches, nuclear structure theory, and geological age estimation due to its radioactivity. The KDK collaboration provides strong evidence for the previously unobserved electron-capture decay to the ground state of argon-40. Statistical analysis shows a nonzero intensity ratio of ground-state electron-captures (IEC0) to excited-state ones (IEC*), with the null hypothesis rejected at 4 & sigma;. This finding has important implications for various fields.

Summary: We investigate two-neutrino (2v beta beta) and neutrinoless double-beta (0v beta beta) decays in the frameworks of the nuclear shell model and proton-neutron quasiparticle random-phase approximation (pnQRPA). By calculating the decay half-lives of various nuclei using the shell model and beta beta emitters with different proton-neutron pairing strengths in the pnQRPA, we find strong linear correlations between 2v beta beta- and 0v beta beta-decay nuclear matrix elements in both methods. We then utilize these correlations and measured 2v beta beta-decay half-lives to predict 0v beta beta-decay matrix elements with theoretical uncertainties based on systematic calculations. Our results incorporate two-body currents and the short-range 0v beta beta-decay operator.

Summary: This study investigates the influence of rotation on the transition temperature of strongly interacting matter produced in non-central heavy ion collisions. By using a holographic description of an AdS black hole, the authors extend the analysis to the more realistic case where the matter spreads over a region around the rotational axis. The results show the coexistence of confined and deconfined phases and are consistent with the concept of local temperature in rotating frames developed by Tolman and Ehrenfest.

Summary: This letter presents the first study of Hawking radiation as a tunneling process within the framework of non-commutative gauge theory of gravity. The non-commutative Schwarzschild black hole is reconstructed using the Seiberg-Witten map and the star product. The emission spectrum of outgoing massless particles is computed using the quantum tunneling mechanism. The results reveal pure thermal radiation in the low-frequency scenario, but a deviation from pure thermal radiation in the high-frequency scenario due to energy conservation. It is also found that noncommutativity enhances the correlations between successively emitted particles.

Summary: The travel times of light signals between two antipodal points on a compact star's surface are calculated for two different trajectories. It is shown that, for highly dense stars, the longer trajectory along the surface may have a shorter travel time as measured by asymptotic observers. A critical value of the dimensionless density-area parameter is determined for constant density stars to distinguish cases where crossing through the star's center or following a semi-circular trajectory on the surface has a shorter travel time as measured by asymptotic observers.
