Parity Violating Asymmetries in Top Pair Production at Hadron Colliders
نویسنده
چکیده
We study loop-induced parity violating asymmetries in the strong production of polarized top quark pairs at pp and pp̄ colliders. The electroweak O(α) corrections to the helicity amplitudes of qq̄ → tt̄ and gg → tt̄ are evaluated in a two Higgs doublet model (2HDM) and the minimal supersymmetric standard model (MSSM). While observables in top quark pair production receive little contribution from standard electroweak interactions, it is possible that they can be significantly enhanced in a 2HDM and the MSSM. We find that the one-loop MSSM electroweak corrections can generate parity violating asymmetries in the total production rate of leftand right-handed top quark pairs up to about 2% at the upgraded Tevatron ( √ S = 2 TeV) and 3% at the LHC ( √ S = 14 TeV).

Mixed QCD and weak corrections to top quark pair production at hadron colliders
The order αs α mixed QCD and weak corrections to top quark pair production by quark antiquark annihilation are computed, keeping the full dependence on the t and t̄ spins. We determine the contributions to the cross section and to single and double top spin asymmetries at the parton level. These results are necessary ingredients for precise standard model predictions of top quark observables, in...

The contribution from the R parity violating interaction, λ ′ ijk LiQjD c k , in the associated production of a top quark (antiquark) with a charm antiquark (quark) is examined for high energy leptonic colliders. We concentrate on the reaction, l − +l + → (t¯ c)+(c ¯ t) → (b ¯ lν¯ c)+(¯ bl¯ νc), associated with the semileptonic top decay. A set of characteristic dynamical distributions for the ...

We investigate the ability of single top quark production via qq → squark → tb and qq̄ → slepton → tb̄ at the LHC and Tevatron to probe the strength of R-parity violating couplings in the minimal supersymmetric model. We found that given the existing bounds on R-parity violating couplings, single top quark production may be greatly enhanced over that predicted by the standard model, and that both...
متن کاملEffects of R-parity violating supersymmetry in top pair production at linear colliders with polarized beams
In the minimal supersymmetric standard model with R-parity violation, the lepton number violating top quark interactions can contribute to the top pair production at a linear collider via tree-level u-channel squark exchange diagrams. We calculate such contributions and find that in the allowed range of these R-violating couplings, the top pair production rate as well as the top quark polarizat...
