Micro Workshop on $B_c^+$ physics at LHCb

Description
It is well agreed that LHCb is today the world leading experiment in the study of $B_c^+$ decays, and it is reasonable to expect that future electron-positron accelerators will contribute marginally to this physics due to the much limited production cross-section, configuring the next few years of data-taking as a crucial step in the characterization of the properties of a meson that can become an important new probe of QCD and electroweak processes when sufficient statistics will be collected.
Indeed, LHCb results show that theoretical predictions on production and branching ratios are not as accurate as they are for other heavy hadrons, which will become a risk when defining exclusive selection strategies at earlier and earlier stages as required by the upcoming LHCb upgrade(s).
The way to a better modelling of the properties of this meson passes through the definition of experimental inputs that, being achievable with the limited statistics available at the end of Run2, will result as constraining as possible for the various theoretical models.
The Bc@LHCb micro workshop is a meeting of theorists and LHCb experts to discuss future theoretical and experimental milestones of the Bc studies in the light of the great improvements on the knowledge of this state that LHCb yielded during the first Run of the LHC.
The event will be structured with alternated experimental and theoretical talks.
An overview of the measurements published by LHCb analysing the 3 fb$^{-1}$ dataset and a talk on the perspectives for Run2 and beyond, including CP violation measurements and searches for doubly-charmed exotic mesons will constitute the experimental contribution.
Theoretical talks include an overview contribution from Likhoded who is updating his works exploiting the results of LHC-Run1, a talk by Berezhnoy focused on production and excited states, and a report by Andrew Lytle about a new activity started at the University of Glasgow to compute $B_c^+$ decay form factors using lattice QCD techniques.
