Detailed Description

template<EV0Type V0Type>
class cbm::algo::kfp::V0FinderCutter< V0Type >

A collection of cuts for V0 production analysis in mCBM.

Template Parameters

V0PdgCode A PDG code of the V0 particle

Note: This class has a mCBM specific implementation, but the scheme of the implementation should be re-used for V0 finding in full CBM.; Conventions: 1) Daughter particles: 0 -> a + b Lambda -> "a" = "pi-", "b" = "proton" Ks -> "a" = "pi-", "b" = "pi+"
