  Current LHC searches for new colored particles generally focus on their pair
production channels and assume any single production to be negligible. We argue
that such an assumption may be unnecessary in some cases. Inclusion of model
dependent single productions in pair production searches (or vice versa) can
give us new information about model parameters or better exclusion limits.
Considering the example of the recent CMS search for first generation scalar
leptoquarks in the pair production channel, we illustrate how single
productions can be systematically included in the signal estimations and
demonstrate how it can affect the mass exclusion limits and give new bounds on
leptoquark-lepton-quark couplings. We also estimate the effect of the pair
production in the more recent CMS search for scalar leptoquarks in single
production channels.
