LHCb Stripping Selections for 2010

Introduction

This page list the stripping selections to be run in 2010. All the selections below are candidates. There's no guarantee that they will be run and when. Stripping selections should be discussed/approved in working group meetings. Summaries should be presented in T&S meetings on a Monday afternoon.

Selections

Stripping lines should be bench-marked against data taken with in July 2010 using $STRIPPINGSELECTIONSROOT/tests/TestMyStrippingLineOnRealData.py. A complete list of retention rates can be found here.

To do list

• Revise the common particles. More sharing can/should be done among similar channels.
• Make selections configurable. An example will be provided soon.
• Make sure one can change the cuts by just loading a new set of cuts, without having to re-release. See HltSettings on how this is handled in Hlt.
• More code should be shared with Hlt
