We perform perturbative QCD factorization of infrared radiations associated with an energetic b quark from a polarized top quark decay, taking the semi-leptonic channel as an example. The resultant…
Energy profile of b-jet for boosted top quarks

We analyse the semileptonic decay of a polarised top-quark with a large veloc- ity based on the perturbative QCD factorisation framework. Thanks to the factorisation and the spin decomposition, the…
Polarized top quarks from new physics: Signals and observables
- Physics
