 Determination of the phase $\phi_{s}$ at LHCb / Batozskaya, Varvara (National Centre for Nuclear Research (PL)) The determination of the mixing-induced $C\!P$-violating phase $\phi_{s}$ in the $B^{0}_{s}-\bar{B}^{0}_{s}$ system is one of the key goals of the LHCb experiment. Using several $B^{0}_{s}$ decay modes it has been measured by the LHCb collaboration exploiting the Run~I data set [...] LHCb-PROC-2018-009; CERN-LHCb-PROC-2018-009.- Geneva : CERN, 2018 - 5.

 Electroweak boson production at LHCb / Sestini, Lorenzo (Universita e INFN, Padova (IT)) The LHCb experiment offers a complementary phase space to ATLAS and CMS to study electroweak processes, thanks to the forward acceptance and the large bandwidth of the trigger allowing low energy thresholds. For this reason electroweak measurements at LHCb can provide unique constraints to the Parton Distribution Functions.

 Fixed target measurements at LHCb for cosmic rays physics / Graziani, Giacomo (Universita e INFN, Firenze (IT)) The LHCb experiment has the unique possibility, among the LHC experiments, to be operated in ﬁxed target mode, using its internal gas target. The energy scale achievable at the LHC, combined with the LHCb forward geometry and detector capabilities, allow to explore particle production in a wide Bjorken-$x$ range at the $\sqrt {s_{NN}} ~$ ~ 100 GeV energy scale, providing novel inputs to nuclear and cosmic ray physics.

 Commissioning of the LHCb detector with ﬁrst data / Graziani, Giacomo (Universita e INFN, Firenze (IT)) We review the different steps of the commissioning work done to have the LHCb detectors ready for the ﬁrst physics at the LHC. The performances of the different subsystems achieved with the ﬁrst collision data are discussed.. LHCb-PROC-2018-004; CERN-LHCb-PROC-2018-004.- Geneva : CERN, 2018 - 4.

 Measurement of antiproton production in p-He collisions and prospects for other inputs to cosmic rays physics from the ﬁxed target program of the LHCb experiment / Graziani, Giacomo (Universita e INFN, Firenze (IT)) The LHCb experiment has the unique possibility, among the LHC experiments, to be operated in ﬁxed target mode, using its internal gas target SMOG. The energy scale achievable at the LHC and the excellent detector capabilities for vertexing, tracking and particle identiﬁcation allow a wealth of measurements of great interest for cosmic ray physics.

 Search for the rare $K^0_S \to \mu^+ \mu^-$ decay / Graziani, Giacomo (Universita e INFN, Firenze (IT)) A search for the decay $K^0_S \to \mu^+ \mu^-$ is performed, based on a data sample corresponding to an integrated luminosity of 1.0 fb$^{−1}$ of pp collisions at $\sqrt s = 7$ TeV collected by the LHCb ex- periment at the Large Hadron Collider. The observed number of candidates is consistent with the background–only hypothesis, yielding an upper limit of $\cal B(K_S^0 \to \mu^+ \mu^−) < 11(9) × 10^{−9}$ at $95~ (90) \%$ conﬁdence level.

 Measurement of antiproton production in $p$–He collisions at LHCb to constrain the secondary cosmic antiproton flux / Graziani, Giacomo (Universita e INFN, Firenze (IT)) The flux of cosmic ray antiprotons is a powerful tool for indirect detection of dark matter. The sensitivity is limited by the uncertainty on the predicted antiproton flux from scattering of primary rays on the interstellar medium.
