This is the first version of a work in progress to enable the analysis of upsilon -> ll (ee, mumu, tautau, mutau, etau) in run3. Of course the hope is that a code review will highlight both the code issues and any issues with the current default cuts applied.
Note that upsilon -> emu is already a part of the qqbar->emu lines.
The bits of code that have been added :
Thanks and Cheers, Raja (and Fergus).
you are apparently using LoKi for combining the particles and then some ThOr filters on top. This is unnecessarily complicated and slows down the process. Have a look at rdbuilder_thor
to see how to use ThOr combiners with a selection instead.
apparently this is deprecated for individual lines at the moment and is applied (as well as a track chi2) on a global level in the reconstruction
You are perfectly right and this is my own fault, have to update qqbar module.
prompt pions will probably dominate the rate. As the tau's have a small but significant lifetime, any requirement on the pi minipchi2 might be crucial to achieve manageable rates
