Upsilon(1S), Upsilon(2S) and Upsilon(3S) cross section measurements in pp collisions at sqrt(s) = 7 TeV
/CMS Collaboration
The differential cross section as a function of transverse momentum for the production of the $\Upsilon(nS)$ ($n$=1,2,3) states decaying into a pair of muons has been measured in pp collisions at $\sqrt{s}$ = 7 TeV using 4.9 fb$^{-1}$ of data collected by the CMS detector. The analysis selected events with dimuon rapidity $|y(\mu\mu)|< 0.6$, and the measurements cover dimuon transverse momentum in the range $p_T(\mu\mu)=$10-100 GeV. [...]

Search for RPV SUSY resonant second generation slepton production in same-sign dimuon events at sqrt(s) = 7 TeV
/CMS Collaboration
A search for resonant production of second generation sleptons ($\tilde{\mu}$,
$\tilde{\nu}_{\mu}$) via the R-parity violating coupling $\lambda'_{211}$,
with two same-sign muons and at least two jets in the final state is
performed. While one muon is expected to be produced directly in the slepton
decay, the second muon and at least two jets are produced in the subsequent
decay of a neutralino or chargino originating from the resonant slepton. [...]

Search for ttH production in events where H decays to photons at 8 TeV collisions
/CMS Collaboration
We present the results of the search for the associated production of the Higgs boson with a $t \bar{t}$ pair, using for the first time the events where the Higgs boson decays to two photons.
To maximize acceptance and sensitivity to such a small signal, we device two different sets of event selection criteria, optimized for leptonic and hadronic $\mathrm{t \bar t}$ decays. We analyze 19.6\,fb$^{-1}$ of 8\,TeV $\mathrm{pp}$ collisions and found no significant excess over the background-only predictions. [...]

Azimuthal angle decorrelations of jets widely separated in rapidity in pp collisions at sqrt{s} = 7 TeV
/CMS Collaboration
The azimuthal angle decorrelations of jets most forward and backward in rapidity (Mueller-Navelet jets) are measured with data collected in pp collisions with the CMS detector at the LHC at $\sqrt{s} = 7$ TeV. The azimutal angle distributions, average cosines of the difference in azimuthal angle between
Mueller-Navelet jets, and ratios of the cosines are measured for jets with $p_{\mathrm{T}} > 35$ GeV and $\vert y \vert < 4.7$.
The results are presented as a function of the rapidity separation $ \Delta y $ between jets, reaching a $ \Delta y $ up to 9.4 for the first time. [...]
