A search for physics beyond the standard model is performed in events with at least three jets and large missing transverse momentum using the data recorded from proton-proton collisions with the CMS detector at the Large Hadron Collider. All backgrounds are estimated from proton-proton collision data. They are: Z+jets events where the Z decaying to neutrinos, W+jets and top events where W...

In this talk, the latest results from CMS on stop pair production are reviewed. We present searches performed for different stop decay modes using data from the 7 and 8 TeV LHC runs.

Naturalness arguments for weak-scale supersymmetry favour supersymmetric partners of the third generation quarks with masses not too far from those of their Standard Model counterparts. Real and virtual production of third generation squarks via decay of a gluino can be significant if the mass of the gluino does not exceed the TeV scale. Top or bottom squarks with masses less than a few...

Pair production of light top squarks at the 8-TeV LHC can be used to probe the gaugino-Higgsino sector of the Minimal Supersymmetric Standard Model. The case where the lightest neutralino is a mixture of Bino and Higgsino, satisfying the thermal dark matter relic density, is investigated. In such a scenario, the lightest top squark decays mostly into (i) a top quark plus the second or third...

A very light scalar top (stop) superpartner is motivated by naturalness and electroweak baryogenesis. When the mass of the stop is less than the sum of the masses of the top quark and the lightest neutralino superpartner, as well as the of the masses of the lightest chargino and the bottom quark, the dominant decay channels of the stop will be three-body, four-body, or flavour violating. In...

In this talk, the latest results from CMS on searches for new physics in final states with four W bosons and multiple b-quarks are presented using up to 20/fb of data from the 8TeV LHC run of 2012. This final state is of special importance in the context of the search for third generation squarks in gluino or sbottom cascade decays. The four W final state is reconstructed in a variety of final...

The top squark (stop) may dominantly decay to a bottom quark and a chargino if the mass difference between the stop and the lightest neutralino is comparable or less than the top quark mass. Such a moderately compressed spectrum is a challenging scenario for the stop search at the Large Hadron Collider, because it is difficult to separate the signals from the top and anti-top background. In...

Vector Boson Fusion (VBF) processes offer a promising avenue to study the neutrlino/chargino system of supersymmetric extensions of the Standard Model at the LHC. Moreover, VBF can probe the stop quark in regions where the stop quark mass is roughly equal to the LSP + top quark mass (the "Stop Rubicon"). A feasibility study for searching for these systems is presented.
