Neutrino Oscillation Prospects with a Dual-Baseline Beam from BNL to SNOLAB and SURF

This paper proposes and simulates a novel dual-baseline neutrino oscillation experiment using a fraction of the Electron-Ion Collider's proton beam to drive a high-intensity GeV-scale beam toward detectors at SNOLAB and SURF, demonstrating that such an extended baseline configuration significantly enhances sensitivity to leptonic CP violation and matter effects.

Stochastic gravitational wave from graviton bremsstrahlung in inflaton decay into massive spin 3/2 particles

This paper investigates the generation of primordial stochastic gravitational waves during the reheating period by calculating the perturbative decay of a coherently oscillating inflaton into massive spin-3/2 particles accompanied by graviton bremsstrahlung, demonstrating that the resulting gravitational wave spectra can provide insights into the microscopic physics of inflation.

Neutrino masses, δPMNSδ_\mathrm{PMNS}, and mββm_{ββ} in SO(10)

This paper presents a comprehensive analysis of a supersymmetric SO(10) model where non-thermal leptogenesis explains the baryon asymmetry, yielding specific predictions for neutrino masses, the CP-violating phase δPMNS\delta_\mathrm{PMNS}, and the neutrinoless double beta decay parameter mββm_{\beta\beta} that remain consistent with JUNO's latest reactor neutrino oscillation data.

Update of the nonlocal sub-leading O1{O}_1-O7{O}_7 contribution to BˉXsγ\bar B \to X_s γ at LO

This paper presents a revised calculation of the complete non-local sub-leading contribution to the inclusive decay BˉXsγ\bar B \to X_s \gamma by removing the previously subtracted local Voloshin term, thereby addressing the high correlation between uncertainties and significantly impacting the estimated range of this contribution.

Analytical study of birefringent cavities for axion-like dark matter search

This study develops a rigorous, nonperturbative framework to quantify how mirror birefringence and polarization misalignment degrade sensitivity in axion-like particle searches, revealing that while misalignment effects can be mitigated through postselection, birefringence introduces a distinct high-mass resonance peak that necessitates careful consideration in high-precision optical-cavity experiments.
