Decfiles for signal analysis of Xi0 -> p+ pi-
Added Xi0_p+pi-=DecProdCut.dec, where the first Xi0/anti-Xi0 of each event should decay via [Xi0 -> p+ pi-]cc
, which is suppressed under the SM. All other Xi0/anti-Xi0 in the event should decay via channels in DECAY.DEC . May add more .dec files if required.
