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 be recast as searches for gluinos in order to extend the sensitivitity. As a demonstration, we show that for [Formula: see text] and [Formula: see text], limits on the stop mass at 8 TeV can be extended by least 300 GeV for a 1.1 TeV gluino using a [Formula: see text] search. At 13 TeV, the effective cross-section for the gluino mediated process is twice the direct stop pair production cross-section, suggesting that direct stop searches could be sensitive to discover new physics earlier than expected.
