Background abundance estimation for Punzi (combinatorial)
Enact a background-abundance estimation for combinatorial candidates in the signal-fit region. This amounts to:
-
fitting the upper-mass band with an exponential -
extrapolating to suitably inversed f: m \to m_{corr}
to get an integral/yield estimate -
would be good to include both CF and DCS data. This a) validates the upper-mass band (above the B_c
); b) also allows to fit more data in the CF mode (expect negligibleB_c
) to validate the extrapolation from a high-mass band fit.
The third item should allows us to appraise the effect of fitting the upper-mass sideband above 6280 MeV, in terms how who minimal alterations of the upper-mass slopes translate to altered shapes whence extrapolating.
Perform then a scan to evaluate Punzi, at the 5\sigma
level, considering a naively combined semi-exclusive signal.
