Abstract

Compressed mass spectra are generally more difficult to identify than spectra with large splittings. In particular, gluino pair production with four high energy top or bottom quarks leaves a striking signature in a detector. However, if any of the mass splittings are compressed, the power of traditional techniques may deteriorate. Searches for direct stop/sbottom pair production can fill in the gaps. As a demonstration, we show that for g~tt~1\tilde{g}\rightarrow t\tilde{t}_1 and mt~1mχ~10m_{\tilde{t}_1}\sim m_{\tilde{\chi}_1^0}, limits on the stop mass at 8 TeV can be extended by least 300 GeV for a 1.1 TeV gluino using a ppt~1t~1pp\rightarrow \tilde{t}_1\tilde{t}_1 search. At 13 TeV, the effective cross section for the gluino mediated process is twice the direct stop/sbottom pair production cross section, suggesting that direct stop/sbottom searches could be sensitive to discover new physics earlier than expected.
