pp → t j ETmiss
We start by investigating a simplified model setup as follows.
The two-squark system is parametrized with the parameters:
After diagonalisation, the physical parameters are:
such that Sq1 = cos(thSq)*St + sin(thSq)*Sc.
Moreover, we consider:
Put model files here…
1. Compute diagonal production cross-sections (at LO): function of mSq1 and mSq2, but independent of thSq.
2. Compute non-diagonal production cross-sections (at LO): function of mSq1, mSq2, and thSq. Evaluate, e.g., for thSq=(0, pi/4, pi/2) and mGl=3 TeV, and check importance w.r.t. diagonal production.
3. Compute branching ratios of Sq1 and Sq2 into t+N1 and into c+N1: function of mSq1, mSq2, thSq, mN1.
4. From the above, deduce cross-sections pp → t t ETmiss
, pp → c c ETmiss
, pp → t c ETmiss
: functions of mSq1, mSq2, thSq, mN1. Make sure to seperate contributions from different subchannels, since this information is necessary to determine the experimental acceptance!
5. Compute the above signal cross-sections in the full model (i.e. with 4×4 mixing) and use the obtained acceptances to deduce the limits.
