A dedicated R&D; is ongoing for the charged particle identification system of the ALICE 3 experiment proposed for the LHC Run 5 and beyond.One of the subsystems for the high-energy charged particle identification will be a Ring-Imaging Cherenkov (RICH) detector.The possibility of integrating Cherenkov-based charged particle timing measurements is currently under study.The proposed system is based on a proximity-focusing RICH configuration including an aerogel radiator separated from a SiPM array layer by an expansion gap. A thin high-refractive index window of transparent material, acting as a second Cherenkov radiator, is glued on the SiPM array to enable time-of-flight measurements of charged particles by exploiting the yield of Cherenkov photons in the thin window.We assembled a small-scale prototype instrumented with different Hamamatsu SiPM array sensors with pitches ranging from 1 to 3 mm, readout by custom boards equipped with the front-end Petiroc 2A ASICs to measure charges and times.The primary Cherenkov radiator consisted of a 2 cm thick aerogel tile, while various window materials, including SiO$_{2}$ and MgF$_{2}$, were used as secondary Cherenkov radiators.The prototype was successfully tested in a campaign at the CERN PS T10 beam line with pions and protons.

The distribution of angular correlations between prompt charm hadrons and primary charged particles in pp collisions is sensitive to the charm-quark hadronisation process. In this letter, charm-baryon correlations are measured for the first time by studying the azimuthal-angle difference between charged particles and prompt $\Lambda_{\rm c}^+$ baryons produced in pp collisions at a centre-of-mass energy $\sqrt{s} = 13$ TeV, with the ALICE detector.
