Measurement of b hadron lifetimes in pp collisions at CMS / Mejia Guisao, Jhovanny Andres (CINVESTAV, IPN) ; De La Cruz-Burelo, Eduard (CINVESTAV, IPN) /CMS Collaboration
Precise measurements of the lifetimes of the $B^0$, $B_s^0$, $\Lambda_b^0$, and $B_c^+$ hadrons using the decay channels $B^0 \to J/\psi K^{*}(892)^0$, $B^0 \to J/\psi K_s^{0}$, $B_s^0 \to J/\psi \pi^+ \pi^-$, $B_s^0 \to J/\psi \phi(1020)$, $\Lambda_b^0 \to J/\psi \Lambda^0$, and $B_c^+ \to J/\psi \pi^+$ were performed. The data sample, corresponding to an integrated luminosity of 19.7 fb$^{-1}$, was collected by the CMS detector at the LHC in proton-proton collisions at $\sqrt{s}=8$ $\textrm{TeV}$. [...]

Heavy ion measurements at ATLAS and CMS / Chapon, Emilien (CERN) /ATLAS and CMS Collaborations
We present an overview of recent results from the ATLAS and CMS collaborations on heavy ion physics. Using data from proton-proton, proton-lead and lead-lead collisions at the LHC, these results help to shed light on the properties of nuclear matter..

Searches with top quarks / Hogan, Julie Managan (Brown U.) /ATLAS and CMS Collaborations
Heavy new physics particles including vector-like quarks, excited quarks, and heavy vector bosons can decay to top quarks alongside other standard model particles. Searches at the CERN LHC in final states with top quarks set strong constraints on the existence of such particles, and measurements of top quark associated production and branching fractions constrain models with flavor-changing neutral currents.

Search for the decay stau --> tau + gravitino in the framework of the Minimal Gauge Mediated SUSY Breaking models / Cavallo, F R (Bologna U. ; INFN, Bologna) ; Navarria, F L (Bologna U. ; INFN, Bologna)
A search for these decays was carried out in the context of Gauge Mediated SUSY Breaking models, using the data collected by DELPHI in 1995 and 1996 at the center of mass energies of 133, 161 and 172 GeV. [...]

Observation of centrality-dependent acoplanarity for muon pairs produced via two-photon scattering in Pb+Pb collisions at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV with the ATLAS detector
This Letter presents a measurement of $\gamma \gamma \rightarrow \mu^{+} \mu^{-}$ production in Pb+Pb collisions recorded by the ATLAS detector at the Large Hadron Collider at $\sqrt{s_{\mathrm{NN}}}=5.02$ TeV with an integrated luminosity of 0.49 nb$^{-1}$. [...]
