The Top Quark at Linear Colliders: QCD Corrections
Cosmin Macesanu
We present a computation of QCD next-to-leading order corrections to the top production and decay process at linear colliders. The top quarks are allowed to be off-shell and the pr…
Gluon Radiation in Top Production and Decay
Cosmin Macesanu, Lynne H. Orr
We present the results of an exact calculation of gluon radiation in top production and decay at high energy electron-positron colliders. We include all spin correlations and inter…
Top and gluons at lepton colliders
Cosmin Macesanu, Lynne H. Orr
In this talk we present results of an exact calculation of gluon radiation in top production and decay at lepton colliders, including all spin correlations and interferences. We co…
Constraints on Heavy Meson Form Factors Derived from QCD Analyticity, Unitarity and Heavy Quark Spin Symmetry
C. Macesanu
Using the analytic properties of two-point functions in QCD, as well as unitarity, bounds on the B meson form factor F(q^2) can be derived. Heavy quark spin symmetry, correctly tak…
