The LHCb Upgrade

TL;DR

The paper discusses upgrades to the LHCb detector aimed at increasing data collection efficiency at higher luminosities, enabling more precise studies of B-meson decays and CP violation.

Contribution

It details the limitations of the current LHCb detector and proposes baseline modifications to significantly enhance its performance at higher luminosities.

Findings

Projected twentyfold increase in hadronic B-decay yields

Tenfold increase in leptonic B-decay yields

Enhanced capability to study rare phenomena

Abstract

The LHCb detector has been designed to study CP violation and other rare phenomena in B-meson decays up to a luminosity of $\sim 5.10^{32}\rm cm^{-2}s^{-1}$. This paper will describe what is limiting LHCb to exploit the much higher luminosities available at the LHC, and what are the baseline modifications which will remedy these limitations. The aim of SuperLHCb is to increase the yields in hadronic B-decay channels by about a factor twenty compared to LHCb, while for channels with leptons in the final state a factor ten increase in statistics is envisaged.
