Description
At hadron colliders, supersymmetric particles are expected to be produced
abundantly in pairs via strong interactions. In this context, top-squark
is of particular interest as a candidate on the lightest squark within
many supersymmetric models.
Given the expected experimental precision, detailed theoretical
predictions are essential.
We present the complete electroweak (EW) corrections to the top-squark
pair production cross section within MSSM
at LHC energies. We show that even though EW
contributions are small for total cross sections, they become
sizeable for differential cross section distributions with respect to
transverse momentum, $p_T$, and invariant mass, $\sqrt{\hat{s}}$, of
the top-squarks for high $p_T$ and high $\sqrt{\hat{s}}$ ranges.
