Properties of Soft Radiation Near tt̄ and W + W − Threshold
نویسنده
چکیده
We discuss the characteristic interference features of soft radiation in the threshold production of heavy unstable particles: soft gluon radiation in e+e− → tt̄ and soft photon radiation in e+e− → W+W−. We show that the heavy particle decay width controls the interference between the emission off the final state particles. As a result, the radiation pattern may provide a way of measuring the decay width of the heavy particles.

Gluon Radiation and Top Width Effects
The large width of the top quark influences the way gluons are radiated in top events, giving rise to interesting interference effects in top production and decay. We discuss top width effects in soft guon radiation in e+e− → tt̄ at high energies and near tt̄ threshold.

Shielding radiation from both x-rays and gamma-rays is important for personnel in medical fields e.g. interventional radiology, nuclear power stations, and other inspection facilities where radiation is involved. Lead is known for its effective shielding property against these high energy radiations, however heaviness and toxicity are its main drawback. In this study effectiveness of non-lead p...
متن کاملLeading Electroweak Corrections to the Production of Heavy Top Quarks at Hadron Colliders
We calculate the electroweak corrections of the order O( 2 t v2 ) to the QCD production of tt̄ pairs via qq̄ → tt̄ at hadron colliders and show that these corrections to the total production rate are small. This correction can be characterized as increasing the cross section most near the threshold region, where top quark signals are important, while the corrections become negative at higher tt̄ en...
