Enhanced trigger system improves detection of hadronic decays.

Enables potential discoveries beyond flavour physics.

Abstract

The LHCb detector at the LHC has shown a very successful initial operation and it is expected that the experiment will accumulate an integrated luminosity in proton-proton collisions of around 1 fb-1 in 2011. The data already collected are being used to pursue the experiment's primary physics goal that is the search for New Physics via the measurement of CP asymmetries and rare decays in the b and c sector. The LHC is already capable of delivering higher luminosity than is currently used at LHCb, and an LHCb upgrade is planned for 2018 which will allow the detector to exploit higher luminosity running, and at the same time to enhance the trigger efficiencies, particularly in the hadronic decay modes. This upgrade will allow the experiment to accumulate an integrated luminosity of more than 50 fb-1 over the following decade, and acquire enormous samples of b and c hadron decays to allow for more precise measurements and a deeper exploration of the flavour sector. In addition, the flexibility of the new proposed trigger together with the unique angular coverage of the LHCb experiment opens up possibilities for interesting discoveries beyond the flavour sector, and will allow LHCb to focus on the physics channels which will be of most interest in the light of the discoveries of the coming decade.
