Abstract

Prompt photons, together with an accompanying jet, have been studied in the photoproduction regime of ep scattering with the ZEUS detector at HERA. Predictions based on leading-logarithm parton-shower Monte Carlo models and next-to-leading-order (NLO) QCD underestimate the gamma+jet cross sections for transverse energies of prompt photons below 7 GeV, while the kT-factorisation QCD calculation agrees with the data in this region.

Evidence for Normal Neutrino Ordering with Combined Atmospheric Neutrino Experiments

We present a combined analysis of the latest publicly available atmospheric neutrino data from Super-Kamiokande including all data-taking stages previous to the gadolinium phase, IceCube-DeepCore, and the six-detection-unit configuration of KM3NeT/ORCA. Our fit uses all event samples simultaneously and treats the systematic uncertainties shared among experiments as fully correlated, while detector-response uncertainties are modeled independently for each experiment. The combined data constrain the atmospheric oscillation parameters to $Δm^2_{31} = 2.44^{+0.06}_{-0.04} \times 10^{-3}\,\mathrm{eV}^2$ and $\sin^2θ_{23} = 0.52^{+0.03}_{-0.04}$, with a precision of $2.2\%$ and $6.1\%$, respectively, which is competitive with current accelerator-based measurements, and independently constrain the $CP$-violating phase to $δ_{CP} = 1.30^{+0.24}_{-0.28}~π$. Finally, comparing the orderings of the neutrino mass spectrum, we find a preference for the normal ordering with $Δχ^2 = 11.0$; further calibrated with pseudoexperiments, we exclude the inverted ordering at $99.95\%$ confidence level ($3.3σ$). In a joint fit including 207 days of JUNO data, we further exclude the inverted ordering at $Δχ^2 = 15.1$, corresponding to $3.9 σ$.

Cross Section Measurements and Searches for New Structures in $e^+e^-$ Annihilations at BESIII

The BESIII collaboration has collected large data samples in the center-of-mass energy range from 1.84 to 4.95 GeV. These data provide a low-background environment and wide energy range for studying the cross sections and the spectroscopy of charmonia. In this article, we review the recent achievements by the BESIII collaboration, including for searching new structures of $XYZ$ particles and the hyperonic production over open-charm threshold.

Study of $Λ$ $CP$ Asymmetry Parameter and Electric Dipole Moment at the Super Tau-Charm Facility

Searching for new mechanisms of $CP$ violation beyond the Standard Model is essential to explain the observed matter-antimatter asymmetry of the universe. By analyzing the full angular distribution of the quantum-entangled $Λ\barΛ$ pairs from $J/ψ$ decays, the preliminary sensitivity of $CP$ asymmetry parameter $A_{CP}$ and Electric Dipole Moment of $Λ$ is studied at the future Super Tau-Charm Facility (STCF). Based on $3.4 \times 10^{12}$ $J/ψ$ events at STCF, the projected sensitivity for $A_{CP}^Λ$ reaches the $10^{-4}$ level, while the $Λ$ EDM can be probed at $10^{-20}$ $e$ cm. These results highly indicate that STCF will provide an unprecedented opportunity to search for new mechanisms of $CP$ violation with an expected world-leading precision.
