00:27:13 Tom Browder: Could include p^(2l+1) phase space factors to penalize complex fits ? 01:06:58 Kirill Chilikin: chi_c0(3930) = X(3915) ??? Mass shift is normal for different channels. 01:27:31 Kirill Chilikin: Efficiency: 1) Integration over MC generated with uniform phase-space distribution or 2) Parameterization based on that MC and 3) should be corrected for data/MC differences 01:29:07 Kirill Chilikin: ... this correction in (3) has some error - one can check the altered efficiemcy based on that error. 01:31:30 Kirill Chilikin: Putting random exotic resonances in: it is the normal procedure when searching and you have to take LEE into account. 01:36:07 Kirill Chilikin: 0+ 01:36:16 Kirill Chilikin: is preferred
