• Low-energy neutrino and dark matter physics with sub-keV germanium detectors

The TEXONO-CDEX Collaboration (Taiwan experiment on neutrino–China dark matter experiment) explores high-purity germanium (HPGe) detection technology to develop a sub-keV threshold detector for pursuing studies on low mass weakly interacting massive particles (WIMPs), properties of neutrino and the possibilities of neutrino-nucleus coherent scattering observation. This article will introduce the facilities of newly established China Jing-Ping Underground Laboratory (CJPL), preliminary result of cosmic ray background studies at CJPL, the dark matter studies pursued at Kuo-Sheng Neutrino Laboratory (KSNL) and research efforts to accomplish our physics goals.

• Target dependence of clan model parameter in 84Kr36–Emulsion interactions at 1 GeV per nucleon

This article focusses on the study of clan model parameters and their target dependence in light of void probability scaling for heavy (Ag and Br) and light (C, N and O) groups of target present in nuclear emulsion detector using 84Kr36 at ∼1 A GeV. The variation of scaled rapidity–gap (rap–gap) probability with single moment combination has been studied. We found that experimental points lie approximately on the negative binomial distribution (NBD) curve, indicating a scaling behaviour. The increase in average clan multiplicities ($\bar{N}$) for interactions with the pseudorapidity interval ($\Delta \eta$) was also observed. The values of $\bar{N}$ for AgBr targets are larger than those for C/N/O target and also average number of particles per clan ($\bar{n}_c$) increases with increase in pseudorapidity interval. We further observed that for a particular target, the average number of particles per clan ($\bar{n}_c$) increases with an increase in the size of projectile nucleus.
