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 $pp\rightarrow p \gamma p \rightarrow \pi^\pm_t t +X$atthe14$TeV$LargeHadronCollider($LHC$) 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 $M_{{\pi }_t}$. Typical $QCD$ correction value is $7% \sim 11%$anddoesnotdependmuchon$\sin\omega$ as well as the forward detector acceptances.
