The Light-only Liquid Xenon (LoLX) experiment is designed to study the properties of light emission and transport in liquid xenon (LXe) using silicon photomultipliers (SiPMs). A particular focus of LoLX is to measure and study Cherenkov and scintillation light emission in LXe. LoLX is currently being upgraded to investigate the long-term behaviour and performance of Hamamatsu VUV4 and FBK...
Using quantum field theory, we calculate the total effect on the photon flux in the microwave background due to some photons being gravitationally scattered toward us and others being gravitationally scattered away from us. The scattering is produced by the density fluctuations which act like point masses in a FLRW background, which can be of either sign. The net effect of having masses of...
The study of muons is very important as they are at the center of several current discrepancies between the experiments and the theoretical predictions, such as the measurement of anomalous magnetic moment and rare decays of B-meson that involve muons. The best limits set in the charged lepton flavour violation are by the muon sector experiments. This is the time to focus on the experiments...
Dark matter annihilation(DMA) provide an promising avenue to detect dark matter particles. Meanwhile, 21-cm line of hydrogen during cosmic dawn have great potential to reveal the information about the early galaxies and stellar formation process.
In this presentation, we elucidate the study using semi-analytic method to model the dark matter annihilation from global background and structure...
The NEWS-G experiment is a dark matter experiment based on gaseous detectors, located at SNO lab. The experiment aims to detect WIMPs by measuring nuclear recoils in noble gases using a spherical proportional counter (SPC) detector, which offers high sensitivity due to its unprecedented low energy threshold. Accurate measurement of the recoil energy requires knowledge of the quenching factor...
NEWS-G is an experiment searching for dark matter using the Spherical Proportional Counter (SPC) technique. Such detectors can operate significant mass of target, of order of kgs with meter size spheres, while keeping single ionization electron detection sensitivity. They can be filled with gaseous targets of low atomic mass such as hydrogen, helium, and neon, giving sensitivity to low mass...
