LAV hit multiplicity

This algorithm aims at rejecting decays with photons at large angle and inelastic interactions. The algorithm uses all LAV stations and corresponds to a cut on the number of LAV hits in time with respect to the L0 trigger.

The cut tested on 2014 data (run 1520) is: Nhits < 2 (see pag 25 here). The algorithm efficiently rejects pipi0 with photon(s) at large angle.

The implementation of the algorithm within the NA62 PC-farm framework is still ongoing.
