Relativistic corrections to exclusive decays and their role in the understanding of the -puzzle
Nikolay Kivel
We study relativistic corrections to exclusive -wave charmonium decays into and final states. The contribution of relative order and the set of associated higher…
A study of relativistic corrections to decay
Nikolay Kivel
We study relativistic corrections in exclusive -wave charmonium decays into proton-antiproton final state. We calculate the NRQCD corrections to the dominant decay amplitude, wh…
A description of charmonia decays within the QCD factorisation framework
Nikolay Kivel
Decays into octet baryon-antibaryons pairs are studied within the QCD factorisation framework. The next-to-leading power correction to the leading-order decay ampl…
Baryon decays within the QCD factorisation framework
Nikolay Kivel
We investigate decays into octet baryon-antibaryons pairs. The decay amplitudes are computed within the collinear QCD factorisation framework. The subleading amplitude, which…
A Study of Power Suppressed Contributions in Decay
Nikolay Kivel
The power suppressed amplitude which describes the Pauli () coupling in the decay is calculated within the effective field theory framework. It is shown th…
Exclusive decays within the effective field theory framework
Nikolay Kivel
We study hadronic decays within the effective field theory framework. We consider the colour-singlet and colour-octet contributions and study t…
