 CP Violation in the $B^0_s$ system in LHCb / Benson, S (University of Edinburgh, UK) Latest LHCb measurements of $CP$ violation in the interference between mixing and decay are presented based on $pp$ collision data collected in 2011 at centre-of-mass energy $\sqrt{s}$ = 7TeV, corresponding to an integrated luminosity of 1.0fb$^{-1}$. A combination of about $27.6k$ $B_s^0\to J/\psi \phi$ and $7.4k$ $B_s^0\to J/\psi \pi\pi$ signal events yield the most accurate measurement of the $CP$-violating phase, $\phi_s^{c\overline{c}s}$.

 Rare decays at LHCb / Polci, Francesco (CNRS/IN2P3, Paris, France) The results on rare decay processes obtained by the LHCb experiment using 1.0 $fb^{-1}$ of $pp$ collisions collected in 2011 at a centre-of-mass energy of $\sqrt{s} = 7 TeV$ are presented. Branching fractions, angular distinctions, CP and isospin asymmetries are investigated to search for new physics effects.. LHCb-PROC-2013-027; CERN-LHCb-PROC-2013-027.- Geneva : CERN, 2013 - 4 p.

 B and C spectroscopy at LHCb / Manca, Giulia (Università degli studi di Cagliari, Italy) We will present recent results in the field of b and c spectroscopy at LHCb, with particular attention to the latest studies on the X(3872) quantum numbers and the $B_c$ new decay modes and mass measurement..

 Precision weak boson production cross-section measurements at LHCb / Barschel, Colin (CERN, Geneva, Switzerland) Precision measurements of weak boson production cross-sections at the Large Hadron Collider (LHC) allow the Standard Model to be tested and parton distribution funtions to be constrained. To achieve this goal an absolute precision of 2% or better is desirable on the experimental measurement. [...] LHCb-PROC-2013-025; CERN-LHCb-PROC-2013-025.- Geneva : CERN, 2013 - 6 p.

 Latest results from LHCb on $B^0_{(s)} \to \mu\mu$ and other very rare decays / Sarti, A (Università di Roma La Sapienza, Roma and Laboratori Nazionali dell'INFN di Frascati, Frascati, Italy) In this review I present the latest updates on the searches for very rare decays to muonic final states performed within the LHCb collaboration using pp collisions at 7 and 8 TeV centre of mass energy. Flavour changing neutral current processes, such as $K^0_s \to \mu^+\mu^-, B^0_{(s)} \to \mu^+\mu^-$ and $B^0_{(s)} \to \mu^+\mu^-\mu^+\mu^-$ are highly suppressed in the Standard Model (SM) and are therefore excellent probes of New Physics (NP) processes or heavy particles that can significantly modify the expected SM rates.

 B decays to charmonia at LHCb / Polyakov, I (Institute of Theoretical and Experimental Physics (ITEP), Moscow, Russia) The recent results from the analyses of B decays into final states containing charmonia resonances at the LHCb detector are presented. The analyses use the data sample collected in 2011, which corresponds to an integrated luminosity up to 1.0 fb$^{−1}$.. LHCb-PROC-2013-023; CERN-LHCb-PROC-2013-023.- Geneva : CERN, 2013 - 11 p.

 CP Violation at LHCb / Steinkamp, Olaf (Physik-Institut, Universität Zürich, Switzerland) Precision measurements of CP violating observables in the mixing and decay of B mesons provide excellent opportunities to search for possible contributions from New Physics beyond the Standard Model. In these proceedings, key measurements pursued by the LHCb collaboration at CERN’s Large Hadron Collider (LHC) are described.

 Testing the Standard Model with rare decays at the LHCb / Graugés, Eugeni (Universitat de Barcelona, Spain) The study of rare decays of B, D and K mesons (as well as $\tau$ leptons) can provide either very stringent tests for the Standard Model or excellent opportunities to search for hints of new physics beyond the SM. A review of the recent results of studies of such rare decays from analysis of $pp$ collision data recorded at the LHCb experiment at CERN, is presented.

 Prospects for time-dependent asymmetries at LHCb / Dupertuis, Frédéric (EPFL, Lausanne, Switzerland) LHCb has been acquiring physics data since 2010 and recorded about 0.04 fb$^{-1}$ in 2010 and 1.1 fb$^{-1}$ in 2011 at center-of-mass energy $\sqrt{s}$ of 7 TeV. In 2012, it is projected to record 2.2 $^{-1}$ at an energy of $\sqrt{s}$ = 8 TeV with a nominal instantaneous luminosity of $\cal{L}$ = 4 x 10$^{32}$ cm $^{-2}$ s$^{-1}$, before a long shutdown of almost two years.
