I'm currently working on the first level trigger (L0) of the LHCb experiment. Below are a list of links to various studies I've been doing ... the list is not complete.

At the time of the LHCb Technical Proposal (2001)
L0 bandwidth division for the hadron and muon triggers (21/10/2002)
The di-muon trigger (08/11/2002)
L0 bandwidth division with multiple interaction events (1/2003)
L0-muon bandwidth division and the staging of the M1 muon station (8/2004)
L0 settings at high luminosity (5/2005)

First investigations (xx/11/2003)

Overlapping sub-triggers and the B_s⁰ → D_s^- K⁺ channel (August 2003)

trigger performance for Brunel v13r1
trigger performance for Brunel v14r0
trigger performance for Brunel v14r2
trigger performance for Brunel v16r4
trigger performance for Brunel v17r3
trigger performance for Brunel v17r4
