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 $pp\rightarrow p \gamma p \rightarrow \pi ^\pm _t t +X$ 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 \omega $ as well as the forward detector acceptances.
