 Dark matter interpretations of ATLAS searches for the electroweak production of supersymmetric particles in $\sqrt{s} = 8$ TeV proton-proton collisions / ATLAS Collaboration A selection of searches by the ATLAS experiment at the LHC for the electroweak production of SUSY particles are used to study their impact on the constraints on dark matter candidates. The searches use $20\,{\rm fb}^{-1}$ of proton-proton collision data at $\sqrt{s}=8$ TeV. [...] arXiv:1608.00872; CERN-EP-2016-165.- Geneva : CERN, 2016 - 25 p. - Published in : J.

 Search for structure in the $B_s^0\pi^\pm$ invariant mass spectrum / LHCb collaboration The $B_s^0\pi^\pm$ invariant mass distribution is investigated in order to search for possible exotic meson states. The analysis is based on a data sample recorded with the LHCb detector corresponding to $3$ fb$^{-1}$ of $pp$ collision data at $\sqrt{s} = 7$ and $8$ TeV.

 Search for new phenomena in different-flavour high-mass dilepton final states in \boldmath{$pp$} collisions at $\sqrt{s}=13$ TeV with the ATLAS detector / ATLAS Collaboration A search is performed for a heavy particle decaying into different flavour dilepton pairs ($e\mu$, $e\tau$ or $\mu\tau$), using 3.2 $fb^{-1}$ of proton--proton collision data at $\sqrt{s}=13$ TeV collected in 2015 by the ATLAS detector at the Large Hadron Collider. No excess over the Standard Model prediction is observed. [...] arXiv:1607.08079; CERN-EP-2016-168.- Geneva : CERN, 2016 - 42 p. - Published in : Eur. Phys. J.

 Measurement of the total cross section from elastic scattering in $pp$ collisions at $\sqrt{s}=8$ TeV with the ATLAS detector / ATLAS Collaboration A measurement of the total $pp$ cross section at the LHC at $\sqrt{s}=8$ TeV is presented. An integrated luminosity of $500$ $\mu$b$^{-1}$ was accumulated in a special run with high-$\beta^{\star}$ beam optics to measure the differential elastic cross section as a function of the Mandelstam momentum transfer variable $t$.

 Measurement of the forward Z boson production cross-section in pp collisions at $\sqrt{s} = 13$ TeV / LHCb Collaboration A measurement of the production cross-section of Z bosons in pp collisions at $\sqrt{s} = 13$ TeV is presented using dimuon and dielectron final states in LHCb data. The cross-section is measured for leptons with pseudorapidities in the range $2.0 < \eta < 4.5$, transverse momenta $p_\text{T} > 20$ GeV and dilepton invariant mass in the range $60 < m(\ell\ell)<120$ GeV [...] arXiv:1607.06495; LHCB-PAPER-2016-021; CERN-EP-2016-170.- Geneva : CERN, 2016 - 32 p. - Published in : J.

 Measurement of exclusive $\gamma\gamma\rightarrow W^+W^-$ production and search for exclusive Higgs boson production in $pp$ collisions at $\sqrt{s} = 8$ TeV using the ATLAS detector / ATLAS Collaboration Searches for exclusively produced $W$ boson pairs in the process $pp(\gamma\gamma) \rightarrow pW^+W^-p$ and exclusively produced Higgs boson in the process $pp(gg) \rightarrow pHp$ have been performed using $e^{\pm}\mu^{\mp}$ final states. These measurements use 20.2 fb$^{-1}$ of $pp$ collisions collected by the ATLAS experiment at a center-of-mass energy $\sqrt{s}=8$ TeV at the LHC.

 Search for Higgs and $Z$ Boson Decays to $\phi\,\gamma$ with the ATLAS Detector / ATLAS Collaboration A search for the decays of the Higgs and $Z$ bosons to a $\phi$ meson and a photon is performed with a $pp$ collision data sample corresponding to an integrated luminosity of $2.7\,\mathrm{fb}^{-1}$ collected at $\sqrt{s}=13\mathrm{TeV}$ with the ATLAS detector at the LHC. No significant excess of events is observed above the background, and 95% confidence level upper limits on the branching fractions of the Higgs and $Z$ boson decays to $\phi\,\gamma$ of $1.4\times10^{-3}$ and $8.3\times10^{-6}$, respectively, are obtained..

 Measurement of the differential cross sections for top quark pair production as a function of kinematic event variables in pp collisions at $\sqrt{s}$ = 7 and 8 TeV / CMS Collaboration Measurements are reported of the normalized differential cross sections for top quark pair production with respect to four kinematic event variables: the missing transverse energy; the scalar sum of the jet transverse momentum (pT); the scalar sum of the pT of all objects in the event; and the pT of leptonically decaying W bosons from top quark decays. The data sample, collected using the CMS detector at the LHC, consists of 5.0 inverse-femtobarns of proton-proton collisions at $\sqrt{s}$ = 7 TeV and 19.7 inverse-femtobarns at $\sqrt{s}$ = 8 TeV.
