Abstract: Abstract We introduce a formalism for describing four-dimensional scattering amplitudes for particles of any mass and spin. This naturally extends the familiar spinor-helicity formalism for massless particles to one where these variables carry an extra… read more here.

Abstract: Abstract We compute all helicity amplitudes for four particle scattering in massless QCD with n f fermion flavours to next-to-next-to-leading order (NNLO) in perturbation theory. In particular, we consider all possible configurations of external quarks… read more here.

DOI: 10.1007/s10773-017-3413-8
Abstract: A novel blind quantum signature scheme based on cluster states is introduced. Cluster states are a type of multi-qubit entangled states and it is more immune to decoherence than other entangled states. The controlled four-particle… read more here.
