 Search for a Multi-Higgs Boson Cascade in W+W− bbar events with the ATLAS detector in pp collisions at √s = 8 TeV A search is presented for new particles in an extension to the Standard Model that includes a heavy Higgs boson (H0), an intermediate charged Higgs boson (H±), and a light Higgs boson (h0).

 Studies of azimuthal anisotropy harmonics in ultra-central PbPb collisions at sqrt(s[NN]) = 2.76 TeV Azimuthal dihadron correlations of charged particles have been measured in PbPb collisions at sqrt(s[NN]) = 2.76 TeV by the CMS collaboration, using data from the 2011 LHC heavy-ion run.

 Impact of Detector Solenoid on the CLIC Luminosity Performance / Levinsen, Yngve Inntjore (CERN) ; Dalena, Barbara (CERN) ; Tomas, Rogelio (CERN) ; Schulte, Daniel (CERN) In order to obtain the necessary luminosity with a reasonable amount of beam power, the Compact Linear Collider (CLIC) design includes an unprecedented collision beam size of {\sigma} = 1 nm vertically and {\sigma} = 45 nm horizontally.

 Scale hierarchy in high-temperature QCD / Akerlund, Oscar ; de Forcrand, Philippe Because of asymptotic freedom, QCD becomes weakly interacting at high temperature: this is the reason for the transition to a deconfined phase in Yang-Mills theory at temperature $T_c$.

 Studies of charmed baryons at LHCb / Ogilvy, S (Glasgow U.) We report a search for the doubly charmed baryon $\Xi_{cc}^{+}$ through the decay $\Xi_{cc}^{+} \to \Lambda_{c}^{+} K^{-} \pi^{+}$, using a data sample corresponding to an integrated luminosity of $0.65~\mathrm{pb^{-1}}$ of $pp$ collisions at $\mathrm{\sqrt{s}} = 7~\mathrm{TeV}$.

 Measurement of electrons from heavy-flavour decays in Pb-Pb collisions at $\sqrt{s_{NN}} = 2.76$ TeV with ALICE / Deepa, Thomas (Utrecht U.) The measurement of heavy-flavour (charm and beauty) production in ultra-relativistic heavy-ion collisions provides an important contribution to the study of the properties of the hot and dense medium created in such collisions.

 Rescuing Quadratic Inflation / Ellis, John ; Fairbairn, Malcolm ; Sueiro, Maria Inflationary models based on a single scalar field $\phi$ with a quadratic potential $V = \frac{1}{2} m^2 \phi^2$ are disfavoured by the recent Planck constraints on the scalar index, $n_s$, and the tensor-to-scalar ratio for cosmological density perturbations, $r_T$.
