Precise photoproduction of the charged top-pions at the LHC with forward detector acceptances

We study the photoproduction of the charged top-pion predicted by the top triangle moose (TTM) model (a deconstructed version of the topcolor-assisted technicolor TC2 model) via the processes pp -> p gamma p -> pi(+/-)(t)t + X at the 14 TeV Large Hadron Collider (LHC) including next-to-leading order (NLO) QCD corrections. Our results show that the production cross sections and distributions are sensitive to the free parameters sin omega and M-pi t. A typical QCD correction value is 7-11 % and this does not depend much on sin. as well as the forward detector acceptances.
