Query: Proton Spin and Tensorgluons   Recently it was suggested that inside the hadrons there are additional
partons - tensorgluons - which carry the same charges as the gluons, but have
larger spin. The nonzero density of tensorgluons can be created inside a
nucleon by radiation of tensorgluons by gluons. Tensorgluons can carry a part
of nucleon momentum together with gluons. Because tensorgluons have a larger
spin, they can influence the spin structure of the nucleon. We analyse a
possible contribution of polarised tensorgluon density to the spin of the
nucleon. This contribution appears in the next to leading order, compared to
the gluons and can provide a substantial screening effect due to the larger
spin of tensorgluons.
