Dark photon count
WebFeb 4, 2024 · TES detectors offer high detection efficiency (above 98%) and the lowest dark count rate. However, these detectors have a large jitter and a long recovery time and require an extremally low temperature (~100 … WebPhoton counting is a technique in which individual photons are counted using a single-photon detector (SPD). A single-photon detector emits a pulse of signal for each detected photon. The counting efficiency is determined by the quantum efficiency and the system's electronic losses.. Many photodetectors can be configured to detect individual photons, …

Due to its interaction with the ordinary, visible photon, such a particle can be experimentally detected via specific signatures. In this book, the authors review the physics of the dark photon from the theoretical and experimental point of view. ...
http://www.coseti.org/radobs42.htm Web1 day ago · We introduce a dark photon considering a U(1) gauge extension of the standard model in particle physics. Provided that the extra U(1) symmetry is unbroken, the dark photon is massless and has no coupling to the standard electromagnetic current. Higher-dimensional operators describe interactions of the massless dark photon with …
WebThe dark count rate is the average rate of registered counts without any incident light. This determines the minimum count rate at which the signal is dominantly caused by real photons.
