5  * InvariantMassDeltaPhiInclusive2Charge.cxx
6  * Based on V Sorin 2014 implementation of InvariantMassInclusive2. For questions contact atlas-trig-l1topo-algcom@cern.ch.
7  *
8  * @brief algorithm calculates the sqr of the INVMASS between two lists and applies invmass criteria. For pairs passing the INVMASS cut a further requirement based on DeltaPhi
9  * is applied, addressing ATR-19377.
10  * Events containing a pair of TGC muons with same charge are rejected
