Search for High-Mass Diphoton Resonances in pp Collisions at sqrt(s)=8 TeV with the CMS Detector /CMS Collaboration
A search for high-mass diphoton resonances is performed in proton-proton collisions at $\sqrt{s}=8$~TeV, with data corresponding to an integrated luminosity of 19.5~fb$^{-1}$, collected by the CMS detector at the CERN Large Hadron Collider. Such a diphoton resonance could be a signature of an excited state of the graviton in the Randall-Sundrum scenario with a warped extra dimension of space. [...]

Search for H/A decaying into Z+A/H, with Z to ll and A/H to fermion pair /CMS Collaboration
A search is performed for a new heavy resonance decaying to a Z boson and a light resonance, where the light resonance decays to either a pair of bottom quarks or a pair of tau leptons and the Z boson decays to two electrons or two muons. The search exploits a data sample collected during 2012 by the CMS experiment at the center-of-mass energy of $\sqrt{s}=$ 8 TeV and corresponding to an integrated luminosity of $\cal L$ = 19.8 $\mathrm{fb^{-1}}$.

Measurements are presented of inclusive differential two b- and two-jet production cross sections as a function of the transverse momentum $p_\text{T}$, pseudorapidity $\eta$, as well as of correlations in azimuthal angle $\phi$, pseudorapidity $\eta$ and $p_\text{T}$ balance among the jets.

Search for supersymmetry in events with soft leptons, low jet multiplicity, and missing transverse momentum in proton-proton collisions at sqrt(s) = 8 TeV /CMS Collaboration
A search for supersymmetry with a compressed mass spectrum is presented. Events are selected using the presence of a high-momentum jet from initial state radiation, high missing energy, and a low-momentum muon, either as the only lepton in the event or accompanied by an electron or muon of the opposite charge. In particular, a scenario of top squark pair production is investigated, where the mass difference to the lightest supersymmetric particle (LSP) is smaller than the mass of the W~boson. In this case the top squarks could undergo four-body decays to $\mathrm{b} \ell \nu + \mathrm{LSP}$. The search is performed in a sample of proton-proton collisions recorded with the CMS detector at a centre-of-mass energy of 8\,TeV and corresponding to an integrated luminosity of 19.7\,$\mathrm{fb}^{-1}$. The results are consistent with the expectation from standard model processes and limits are set on the production cross section in the plane of the top squark vs. LSP masses. Assuming a 100\% branching ratio of the four-body decay top squark masses below 316\,GeV are excluded at 95\%~confidence level for a mass difference to the LSP of about 25\,GeV. Results are also interpreted under the assumption of chargino-neutralino production, with subsequent decays via sleptons or sneutrinos..
