microDST

The microDST uses the standard LHCb DST format to store all information about the particles of interest. Links pointing to the original information ensure that all information is still available. Further information can be found on the microDST page.

Multivariate Selections

The multi variate selections use the result of training datasets for selecting signal events and rejecting background events for each physics channel within the DaVinci framework. Further information on this topic can be found on MultiVariateSelections page.
