Article Synopsis
  • * The study introduces enhanced modeling techniques for neutrino flux and detector response, and it distinguishes between starting (inside) and throughgoing (outside) neutrino interaction events to improve energy resolution.
  • * The findings indicate a best-fit point for the 3+1 model with sin²(2θ_{24})=0.16 and Δm_{41}²=3.5 eV², supporting previous studies while showing consistency with no evidence of sterile neutrinos, as reflected

Jerseys are the second most popular breed in the US dairy industry, yet there are few studies that directly compare their behavior with Holsteins. The objective of this observational study was to describe differences in the standing behavior of healthy Jersey and Holstein dairy cows during the periparturient period. A total of 51 Jerseys (11 primiparous [PP] and 40 multiparous [MP]) and 36 Holsteins (8 PP, 28 MP) were used for this analysis.

Article Synopsis
  • - The study presents a measurement of astrophysical tau neutrinos using 9.7 years of data from the IceCube observatory, identifying seven candidate events with energies between 20 TeV and 1 PeV.
  • - Convolutional neural networks were used to analyze simulated event images, helping to estimate the parent tau neutrino energy to be around 200 TeV while facing a background of about 0.5 events primarily from non-tau astrophysical neutrinos.
  • - The results confirmed the presence of astrophysical tau neutrinos at a 5σ significance level, aligning with existing IceCube measurements and theoretical predictions regarding neutrino flux and oscillations.

Article Synopsis
  • - The T2K experiment reports enhanced measurements of neutrino oscillation parameters through new proton-on-target (POT) neutrino data, significantly improving analysis methods with a major focus on the near detector's new selection procedures.
  • - This analysis is the first to utilize data from the NA61/SHINE experiment, helping to refine the neutrino flux model and enhance the neutrino interaction model by incorporating new nuclear effects.
  • - Both frequentist and Bayesian approaches indicate a preference for normal mass ordering and a nearly maximal CP-violating phase, with notable exclusions and constraints on certain parameters aligning with past T2K studies.
