hi,
in the link which u have send to me it is written

In order to reduce combinatorics, a cut on the invariant mass can be applied very easily by defining a mass selector with
center of selection window
v
RhoMassParticleSelector *jpsiMassSel=new RhoMassParticleSelector("jpsi",3.096,1.0);
^
full width of window
how to decide this center and width & is this the only cut for invariant mass
