Observation of $\Lambda_b^0\rightarrow D^+ p \pi^-\pi^-$ and $\Lambda_b^0\rightarrow D^{*+} p \pi^-\pi^-$ decays
The multihadron decays $\Lambda_b^0\rightarrow D^+ p \pi^-\pi^-$ and $\Lambda_b^0\rightarrow D^{*+} p \pi^-\pi^-$ are observed in data corresponding to an integrated luminosity of 3fb$^{-1}$, collected in proton-proton collisions at centre-of-mass energies of 7 and 8TeV by the LHCb detector [...]

Transient Monte Carlo Simulations for the Optimisation and Characterisation of Monolithic Silicon Sensors / Ballabriga Sune, Rafael (CERN) ; Braach, Justus (Hamburg University (DE)) ; Buschmann, Eric (CERN) ; Campbell, Michael (CERN) ; Dannheim, Dominik (CERN) ; Dort, Katharina (Justus-Liebig-Universitaet Giessen (DE)) ; Huth, Lennart (Deutsches Elektronen-Synchrotron (DE)) ; Kremastiotis, Iraklis (KIT - Karlsruhe Institute of Technology (DE)) ; Kroeger, Jens (Ruprecht Karls Universitaet Heidelberg (DE)) ; Linssen, Lucie (CERN) et al.
An ever-increasing demand for high-performance silicon sensors requires complex sensor designs that are challenging to simulate and model. The combination of electrostatic finite element simulations with a transient Monte Carlo approach provides simultaneous access to precise sensor modelling and high statistics. [...]

Deep inelastic scattering off quark-gluon plasma and its photon emissivity / Cè, Marco ; Harris, Tim ; Meyer, Harvey B. ; Toniato, Arianna ; Török, Csaba
The photon emissivity of quark-gluon plasma probes the interactions in the medium and differs qualitatively between a weakly coupled and a strongly coupled plasma in the soft-photon regime. [...]

Combined searches for dark matter in dwarf spheroidal galaxies observed with the MAGIC telescopes, including new data from Coma Berenices and Draco / MAGIC Collaboration
Milky Way dwarf spheroidal galaxies (dSphs) are among the best candidates to search for signals of dark matter annihilation with Imaging Atmospheric Cherenkov Telescopes, given their high mass-to-light ratios and the fact that they are free of astrophysical gamma-ray emitting sources. [...]
