LHCb Upstream Tracker
 Reference: Poster-2014-445 Keywords:  lhcb  upstream tracker Created: 2014. -1 p Creator(s): Gandini, Paolo The LHCb upgrade requires replacing the silicon strip tracker between the vertex locator (VELO) and the magnet. A new design has been developed and tested based on the "stave" concept planned for the ATLAS upgrade. Related links:Conference LHCb Poster © CERN Geneva Access to files

LHCb Measurement of the CKM angle $\gamma$ at LHCb
 Reference: Poster-2014-443 Keywords:  LHCb Created: 2014. -1 p Creator(s): Ali, S In this poster we present the latest result by the LHCb collaboration in determining the CKM angle $\gamma$ ($(67.1 \pm 12)^{\circ}$). The result is determined by combining several $B \to Dh$ analyses. Latest results from the decay time dependent $B_{s} \to D_{s}K$ analysis is also reported, along with a few other decay channels interesting for determination of $\gamma$ in the future.

LHCb : Measuring $CP$ violation with $\Delta A_{CP}$ at LHCb
 Reference: Poster-2014-442 Keywords:  LHCb Created: 2014. -1 p Creator(s): Pearce, A Measurements are presented of direct $CP$ violation in $D^{0}$ meson decays in LHCb, using the $\Delta A_{CP}$ technique, and a proposal is outlined to make similar measurements in the decays of the charmed baryon $\Lambda_{c}^{+}$. The motivations for use of the $\Delta A_{CP}$ method are discussed, along with the current results and future prospects. Related links:50 Years of CP Violation © CERN Geneva Access to files

LHCb : Search for Lepton Flavour Violation at LHCb
 Reference: Poster-2014-441 Keywords:  LHCb Created: 2014. -1 p Creator(s): Rives Molina, Vicente The observation of neutrino oscillations has re-opened the case for searches of lepton-flavour violating decays. We report on recent results on searches for short or long-lived Majorana heavy neutrinos in B&arr;μμπ and τ→μμμ decays Related links:ICHEP2014 © CERN Geneva Access to files

LHCB Searches for long-lived heavy particles at LHCb
 Reference: Poster-2014-440 Keywords:  LHCb Created: 2014. -1 p Creator(s): Marin Benito, Carla Its forward acceptance and good resolution allow LHCb to perform competitive searches for heavy particles beyond the Standard Model. We report a search for the stau particle with the LHCb detector and give our prospects for searches of Hidden Valley particles. Related links:ICHEP2014 Conference © CERN Geneva Access to files

LHCb: Dynamically Adaptive Header Generator and Front-End Source Emulator for a 100 Gbps FPGA Based DAQ
LHCb: Searches for $\Lambda^0_b$ and $\Xi^0_b$ decays to $K^0_{\mathrm{S}}p\pi^-$ and $K^0_{\mathrm{S}}pK^-$ final states with first observation of the $\Lambda^0_b \rightarrow K^0_{\mathrm{S}}p\pi^-$ decay
 Reference: Poster-2014-438 Keywords:  flavour physics Created: 2014. -1 p Creator(s): Whitehead, M A search for previously unobserved decays of beauty baryons to the final states $K^0_{\mathrm{S}}p\pi^-$ and $K^0_{\mathrm{S}}pK^-$ is reported. The analysis is based on a data sample corresponding to an integrated luminosity of $1.0\,\mathrm{fb}^{-1}$ of $pp$ collisions. The $\Lambda^0_b \rightarrow K^0_{\mathrm{S}}p\pi^-$ decay is observed for the first time with a significance of $8.6\,\sigma$, and a measurement is made of the $CP$ asymmetry, which is consistent with zero. No significant signals are seen for $\Lambda^0_b \rightarrow K^0_{\mathrm{S}}pK^-$ decays, $\Xi^0_b$ decays to both $K^0_{\mathrm{S}}p\pi^-$ and $K^0_{\mathrm{S}}pK^-$ final states, and the $\Lambda^0_b \rightarrow D^-_s (K^0_{\mathrm{S}}K^-)p decay, and upper limits on their branching fractions are reported.

The analysis is based on a data sample corresponding to an integrated luminosity of 1.6 nb$^{−1}$. The forward-backward production ratio and the nuclear modification factor are determined for$J/\psi$and Y(1S). Indication of forward backward production asymmetry is observed. There is also an indication of$J/\psi\$ and Y(1S)production suppression with respect to proton-proton collisions in forward region and anti-shadowing effect in backward region.
