Physics at CLIC / Redford, Sophie (CERN) ; Roloff, Philipp Gerhard (CERN)
CLIC is a concept for a future linear collider which would use two-beam acceleration to produce e+e- collisions with a centre-of-mass energy of 3 TeV. A staging scenario would also provide collisions at lower centre-of-mass energies, provisionally 350 GeV and 1.4 TeV. [...]

Search for third-generation scalar leptoquarks in the t$\tau$ channel in proton-proton collisions at $\sqrt{s}$ = 8 TeV
A search for pair production of third-generation scalar leptoquarks decaying to top quark and $\tau$ lepton pairs is presented using proton-proton collision data at a center-of-mass energy of $\sqrt{s}$ = 8 TeV collected with the CMS detector at the LHC and corresponding to an integrated luminosity of 19.7 fb$^{-1}$.

Measurement of diffractive dissociation cross sections in pp collisions at $\sqrt{s}$ =7 TeV
Measurements of diffractive dissociation cross sections in pp collisions at $\sqrt{s}$ = 7 TeV are presented in kinematic regions defined by the masses $M_X$ and $M_Y$ of the two final-state hadronic systems separated by the largest rapidity gap in the event. [...]

QCD phase diagram from the lattice at strong coupling / de Forcrand, Philippe (ETH, Zurich ; CERN) ; Philipsen, Owe (Frankfurt U.) ; Unger, Wolfgang (Frankfurt U.)
The phase diagram of lattice QCD in the strong coupling limit can be measured in the full $\mu$-$T$ plane, also in the chiral limit. [...]

Search for low-scale gravity signatures in multi-jet final states with the ATLAS detector at $\sqrt{s}$ = 8 TeV
We search for evidence of physics beyond the Standard Model in the production of final states with multiple high transverse momentum jets, using 20.3 $fb^{-1}$ of proton-proton collision data recorded by the ATLAS detector at $\sqrt{s}$ = 8 TeV. [...]

Searches for third-generation squark production in fully hadronic final states in proton-proton collisions at $\sqrt{s}$ = 8 TeV / CMS Collaboration
Searches for third-generation squarks in fully hadronic final states are presented using data samples corresponding to integrated luminosities of 19.4 or 19.7 fb$^{-1}$, collected at a centre-of-mass energy of 8 TeV with the CMS detector at the LHC. [...]

Observation of the ${B^0 \to \rho^0 \rho^0}$ decay from an amplitude analysis of ${B^0 \to (\pi^+\pi^-)(\pi^+\pi^-)}$ decays / LHCb collaboration
Proton-proton collision data recorded in 2011 and 2012 by the LHCb experiment, corresponding to an integrated luminosity of 3.0 fb$^{-1}$i, are analysed to search for the charmless ${B^0 \to \rho^0 \rho^0}$ decay. [...]

Rapidity and transverse-momentum dependence of the inclusive J/$\mathbf{\psi}$ nuclear modification factor in p-Pb collisions at $\mathbf{\sqrt{\textit{s}_{NN}}}=5.02$ TeV / ALICE Collaboration
We have studied the transverse-momentum ($p_{\rm T}$) dependence of the inclusive J/$\psi$ production in p-Pb collisions at $\sqrt{s_{\rm NN}} = 5.02$ TeV, in three center-of-mass rapidity ($y_{\rm cms}$) regions, down to zero $p_{\rm T}$. [...]

Semiclassical S-matrix for black holes / Bezrukov, Fedor (CERN ; Connecticut U. ; RIKEN BNL) ; Levkov, Dmitry (Moscow, INR) ; Sibiryakov, Sergey (CERN ; Moscow, INR ; Ecole Polytechnique, Lausanne)
We propose a semiclassical method to calculate S-matrix elements for two-stage gravitational transitions involving matter collapse into a black hole and evaporation of the latter. [...]
