Transverse momentum and rapidity distributions of top quarks in pair and single top quark production within the non-commutative standard model at the LHC
This paper presents a comprehensive study of top quark phenomenology within
the Non-Commutative Standard Model. We calculate non-commutative corrections to
the squared amplitudes for top quark pair production, as well as for single top
quark production via the $t$-channel and $tW$-channel, while noting that the
$s$-channel remains unaffected by non-commutative geometry. Utilizing
MadGraph5_aMC@NLO, we determine total cross-sections at various center-of-mass
energies and examine differential distributions in transverse momentum and
rapidity at leading order in both the strong coupling $\alpha_S$ and the
non-commutative parameter $\Theta$. For single top production in the
$t$-channel, a matching technique is employed to extend the validity of the
distribution to low $p_t^{top}$ values through resummation. We also compare the
non-commutative corrections with higher-order QCD corrections obtained at NLO
using MCFM and at NNLO from existing literature. Our findings reveal
significant deviations arising from non-commutative geometry at high energies,
providing insights into potential new physics at energy scales accessible by
current and future colliders.
