1. Constraints on Neutrino Secret Interactionsfrom Multi-messenger neutrinos scattering on CνB

Maria Petropavlova (Faculty of Mathematics and Physics at Charles University, Institute of Experimental and Applied Physics (IEAP) at the Czech Technical University in Prague)

We present new constraints on neutrino secret interactions ($\nu$SI) by studying high-energy neutrinos from well-known astrophysical sources, such as SN1987A, the blazars TXS $0506+056$ and PKS $0735+178$, NGC 1068 and KM3-230213A neutrino event. Our analysis focuses on Dirac neutrinos interacting with a massive spin-one boson as they propagate through the Cosmic Neutrino Background (C$\nu$B)....

5. Insights into Lithium-Germanium Interface Dynamics in HPGe Detectors: A GEANT4 Study

Ms Soni Devi (Indian Institute of Technology Ropar, Rupnagar - 140 001, Punjab, India)

Geometry-dependent performance evaluation of an HPGe detector is crucial for low-level $\gamma$-ray spectrometry, rare decay studies [Su, J., et al. 2014. NIM A, 763, 364–371], and environmental radioactivity assessments [Tarabini, E., et al. 2023. Appl. Radiat. Isot., 196, 110768]. In this study, the thickness of the top dead layer ($\textrm{t}_{\textrm{d}}$) of an HPGe detector was estimated...
