The ePIC detector, at the Electron Ion Collider (EIC), is capable of delivering the entire EIC physics programme. In EIC, efficient Particle IDentification (PID) plays a key role for a large portion of the overall physics scope. In the forward or hadron going direction, where high momentum final state hadrons have to be identified, a dual radiator ring imaging Cherenkov (dRICH) detector is considered to perform \(\pi /K/p\) identification from \(\sim \) 3 GeV/c and up to 50 GeV/c over a wide pseudorapidity range (1.5 \(<\eta <\) 3.5). Apart from hadron identification the dRICH is expected to provide excellent pion rejection to boost the calorimeter and tracking systems in identifying electrons from few hundreds of MeV/c up to about 15 GeV/c. In this work, we highlight the performance of the ePIC dRICH detector by estimating the separation power from the mean and the resolution of the reconstructed Cherenkov angle. The numbers are extracted from a study using the full ePIC simulation framework. We also present the results of our analysis with aerogels of two different refractive indices (n = 1.019 and n = 1.026) and compare them based on their performance in the context of the PID capability of the dRICH.
