Spin-Spin Correlations of Top Quark Pairs at Hadron Colliders
نویسنده
چکیده
Top quark pairs are produced with strongly correlated spins in the partonic reactions qq̄ → tt̄ and gg → tt̄. A complete description of these effects in terms of the spin density matrix of the tt̄ system in leading order QCD is given. We further discuss the prospects to observe the spin-spin correlations at pp̄ and pp colliders by measuring suitable angular correlations among the t and t̄ decay products.

Angular correlations in top quark pair production and decay at hadron colliders.
We show how to observe sizable angular correlations between the decay products of the top quark and those of the anti-top quark in top quark pair production and decay at hadron colliders. These correlations result from the large asymmetry in the rate for producing like-spin versus unlike-spin top quark pairs provided the appropriate spin axes are used. The effects of new physics at production o...
متن کاملSpin properties of top quark pairs produced at hadron colliders
We discuss the spin properties of top quark pairs produced at hadron colliders at next-to-leading order in the coupling constant αs of the strong interaction. Specifically we present, for some decay channels, results for differential angular distributions that are sensitive to tt̄ spin correlations. PACS number(s): 12.38.Bx, 13.88.+e, 14.65.Ha

Next-to-leading order QCD corrections to top quark spin correlations at hadron colliders: the reactions q ¯ q → t ¯ t(g) Abstract: Future hadron collider experiments are expected to record large to huge samples of t ¯ t events. The analysis of these data with respect to t ¯ t spin-spin correlations requires precise predictions of the production of these quark pairs in a general spin configurati...
متن کاملSpin Effects in Processes of Single Top Quark Production at Hadron Colliders
We investigate spin properties of single top quark production at hadron colliders. Based on an analogy with single top production and polarized top quark decay, we reproduce in a simple way the results by G. Mahlon and S. Parke on the existence of preferred axes for the decomposition of the top quark spin. For the W ∗and W-g-fusion production modes these axes are related to the down-type quark ...
