XII International Workshop on Ring Imaging Cherenkov Detectors - RICH2025

As RICH detector technologies evolve and data volumes increase, innovative pattern recognition and data analysis methods have become essential to fully exploit the capabilities of RICH systems. This talk presents an overview of recent developments in this domain, highlighting both methodological advancements and practical implementations across current and next-generation experiments. We...

NA62 is the last generation kaon experiment at the CERN SPS aiming to study the ultra-rare $K^+ \rightarrow \pi^+ \nu \overline{\nu}$ decay, measuring its branching ratio with a precision better than $20\%$.
One of the challenging aspect of NA62 is the suppression of background decay channels with branching ratios up to 10 orders of magnitude higher than the signal and with a similar...

The LHCb RICH detectors will introduce timing information $\mathcal{O}(100\,$ps) for every detected photon during the LHC Run 4. Using the RICH time information, the primary vertex time (PV t$_0$) can be estimated for the first time in LHCb, which is a key input parameter for exploiting fast-timing techniques in the experiment. In the RICH reconstruction algorithm, an object called a photon...

The ePIC experiment at EIC integrates a dual-radiator RICH (dRICH) detector for particle identification in the forward region. The detector will use silicon photomul tipliers (SiPMs) to detect Cherenkov radiation with single-photon sensitivity over a surface of ∼3 m2. The ∼320k detector channels will be readout by 4,992 Front End Boards (FEBs); each of the 1,248 Readout Boards (RDOs) will...

Particle Identification (PID) will be crucial in Future Circular Colliders (FCC-ee) or other Higgs Factory experiments for precision studies involving heavy-flavour particles in Z decays, as well as jet flavour tagging in the decays of Higgs, W, and top particles.
In this context, a novel Ring Imaging Cherenkov (RICH) detector concept, named ARC (Array of RICH Cells), has been proposed.
The...
