Test of lepton universality inside the \PJpsi region as a basis for further research away from charmonium resonances. / Wojtas, Maksymilian
The ratio $R_L$ of the branching fractions of the two rare decay channels $\PbgL\to\Pp\PK\Pmuon\APmuon$ and $\PbgL\to\Pp\PK\Pelectron\APelectron$ is expected to be unity in SM due to lepton universality [...]

Upstream Tracking and the Decay $B^{0} \to K^{+}\pi^{-}\mu^{+}\mu^{-}$ at the LHCb Experiment / Bowen, Espen Eie
The LHCb detector is a single-arm forward spectrometer covering the pseudorapidity range $2 < \eta < 5$, designed to search for indirect evidence of New Physics in $C\!P$ violation and rare decays of beauty and charm hadrons [...]

Flavour studies with LHCb: b-meson mixing, lepton-flavour violation and the velo upgrade / Bird, Thomas
Semileptonic $B$ decays of the type $B^0_q\to{}D^-_q\mu^+\nu$ (where $D^-\to{}K^-K^+\pi^-$) are selected and their lifetimes are corrected using a statistical simulation-based correction called the $k$-factor [...]

Search for the decay $B^+ \to D^{*-}K^+\pi^+$ / Rera, Ronnie P
The $B^+ \to D^{*-}K^+\pi^+$ decay is searched for in a sample, collected with the LHCb detector, of proton-proton collision data at centre-of-mass energies $\sqrt{s} = 7$ and $8 ~\text {TeV}$, corresponding to an integrated luminosity of $3 \text {fb}$ [...]
