Multicore job scheduling in the Worldwide LHC Computing Grid / Forti, A (Manchester U.) ; Yzquierdo, A P (PIC, Bellaterra ; Madrid, CIEMAT) ; Hartmann, T (KIT, Karlsruhe, SCC) ; Alef, M (KIT, Karlsruhe, SCC) ; Lahiff, A (Rutherford) ; Templon, J (NIKHEF, Amsterdam) ; Pra, S Dal (INFN, CNAF) ; Gila, M (Zurich, ETH-CSCS/SCSC) ; Skipsey, S (Glasgow U.) ; Acosta-Silva, C (PIC, Bellaterra ; Barcelona, IFAE) et al.
After the successful first run of the LHC, data taking is scheduled to restart in Summer 2015 with experimental conditions leading to increased data volumes and event complexity. In order to process the data generated in such scenario and exploit the multicore architectures of current CPUs, the LHC experiments have developed parallelized software for data reconstruction and simulation.

The production deployment of IPv6 on WLCG / Bernier, J (CC, Villeurbanne) ; Campana, S (CERN) ; Chadwick, K (Fermilab) ; Chudoba, J (Prague, Inst. Phys.) ; Dewhurst, A (Rutherford) ; Eliáš, M (Prague, Inst. Phys.) ; Fayer, S (Imperial Coll., London) ; Finnern, T (DESY) ; Grigoras, C (CERN) ; Hartmann, T (KIT, Karlsruhe, IKP) et al.
The world is rapidly running out of IPv4 addresses, the number of IPv6 end systems connected to the internet is increasing, WLCG and the LHC experiments may soon have access to worker nodes and/or virtual machines (VMs) possessing only an IPv6 routable address. The HEPiX IPv6 Working Group has been investigating, testing and planning for dual-stack services on WLCG for several years. [...]

Model-independent confirmation of the $Z(4430)^-$ state / LHCb collaboration
The decay $B^0\to \psi(2S) K^+\pi^-$ is analyzed using $\rm 3~fb^{-1}$ of $pp$ collision data collected with the LHCb detector. A model-independent description of the $\psi(2S) \pi$ mass spectrum is obtained, using as input the $K\pi$ mass spectrum and angular distribution derived directly from data, without requiring a theoretical description of resonance shapes or their interference.

Measurement of $CP$ violation and constraints on the CKM angle $\gamma$ in $B^{\pm}\rightarrow D K^{\pm}$ with $D \rightarrow K_S^0 \pi^+ \pi^-$ decays / LHCb collaboration
A model-dependent amplitude analysis of $B^{\pm} \rightarrow D K^{\pm}$ with $D \rightarrow K_S^0 \pi^+ \pi^-$ decays is performed using proton-proton collision data, corresponding to an integrated luminosity of $1$ fb$^{-1}$, recorded by LHCb at a centre-of-mass energy of $7$ TeV in $2011$. Values of the $CP$ violation observables $x_{\pm}$ and $y_{\pm}$, which are sensitive to the CKM angle $\gamma$, are measured to be \begin{align*} x_- &= +0.027 \pm 0.044 ^{+0.010}_{-0.008} \pm 0.001, \\ y_- &= +0.013 \pm 0.048 ^{+0.009}_{-0.007} \pm 0.003, \\ x_+ &= -0.084 \pm 0.045 \pm 0.009 \pm 0.005, \\ y_+ &= -0.032 \pm 0.048 ^{+0.010}_{-0.009} \pm 0.008, \end{align*} where the first uncertainty is statistical, the second systematic and the third arises from the uncertainty of the $D \rightarrow K_S^0 \pi^+ \pi^-$ amplitude model.

Effective lifetime measurements in the $B_{s}^{0} \rightarrow K^{+}K^{-}$, $B^{0} \rightarrow K^{+}\pi^{-}$ and $B_{s}^{0} \rightarrow \pi^{+}K^{-}$ decays / LHCb collaboration
Measurements of the effective lifetimes in the $B_{s}^{0} \rightarrow K^{+}K^{-}$, $B^{0} \rightarrow K^{+}\pi^{-}$ and $B_{s}^{0} \rightarrow \pi^{+}K^{-}$ decays are presented using $1.0~\mathrm{fb^{-1}}$ of $pp$ collision data collected at a centre-of-mass energy of 7 TeV by the LHCb experiment. The analysis uses a data-driven approach to correct for the decay time acceptance. [...]

Search for $CP$ violation in $D^{\pm}\rightarrow K^0_S K^{\pm}$ and $D^{\pm}_{s}\rightarrow K^0_S \pi^{\pm}$ decays / LHCb collaboration
A search for $CP$ violation in Cabibbo-suppressed $D^{\pm}\rightarrow K^0_S K^{\pm}$ and $D^{\pm}_{s}\rightarrow K^0_S \pi^{\pm}$ decays is performed using $pp$ collision data, corresponding to an integrated luminosity of 3~fb$^{-1}$, recorded by the LHCb experiment. The individual $CP$-violating asymmetries are measured to be \begin{eqnarray*} \mathcal{A}_{CP}^{D^{\pm}\rightarrow K^0_S K^{\pm}} & = & (+0.03 \pm 0.17 \pm 0.14) \% \\ \mathcal{A}_{CP}^{D^{\pm}_s\rightarrow K^0_S \pi^{\pm}} & = & (+0.38 \pm 0.46 \pm 0.17) \%, \end{eqnarray*} assuming that $CP$ violation in the Cabibbo-favoured decays is negligible.

Observation of the $\Lambda_b^0 \rightarrow J/\psi p \pi^-$ decay / LHCb collaboration
The first observation of the Cabibbo-suppressed decay $\Lambda_b^0\rightarrow J/\psi p \pi^-$ is reported using a data sample of proton-proton collisions at 7 and 8 TeV, corresponding to an integrated luminosity of 3 $\rm fb^{-1}$. A prominent signal is observed and the branching fraction relative to the decay mode $\Lambda_b^0\rightarrow J/\psi p K^-$ is determined to be $$ \frac{{\cal B}(\Lambda_b^0\rightarrow J/\psi p \pi^-)}{{\cal B}(\Lambda_b^0\rightarrow J/\psi p K^-)}=0.0824\pm0.0025\:(\text{stat})\pm0.0042\:(\text{syst}).

Precision measurement of the mass and lifetime of the $\Xi_b^0$ baryon / LHCb collaboration
Using a proton-proton collision data sample corresponding to an integrated luminosity of 3 fb$^{-1}$ collected by LHCb at center-of-mass energies of 7 and 8 TeV, about 3800 $\Xi_b^0\to\Xi_c^+\pi^-$, $\Xi_c^+\to pK^-\pi^+$ signal decays are reconstructed. From this sample, the first measurement of the $\Xi_b^0$ baryon lifetime is made, relative to that of the $\Lambda_b^0$ baryon. [...]
