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

Abstract

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 $pp\to p\gamma p\to {\pi }_t^{\pm }t+X$ 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 $M_{{\pi }_t}$. Typical $QCD$ correction value is $7\%\sim 11\%$ and does not depend much on $\sin \omega$ as well as the forward detector acceptances.
