Quasi-plane waves for spin 1 field in Lobachevsky space and a generalized helicity operator
Quasi-plane waves spin 1 field Lobachevsky space generalized helicity operator Mathematical Physics
2012/5/9
Spin 1 particle is investigated in 3-dimensional curved space of constant negative curvature. An extended helicity operator is defined and the variables are separated in a tetrad-based 10-dimensional ...
We investigate two seemingly disjoint definitions of helicity, one commonly used in particle physics, the other one used when studying bilinear covariants of Clifford algebras. We can prove that the `...

We present a measurement of the helicity of the W boson produced in top quark decays using
t¯t decays in the ℓ+jets and dilepton final states selected from a sample of 5.4 fb−1 of co...

Phase transition to the state with nonzero average helicity in dense neutron matter
Phase transition state with nonzero average helicity dense neutron matter
2011/1/6
The possibility of the appearance of the states with a nonzero average helicity in neutron matter is studied in the model with the Skyrme effective interaction. By providing the analysis of the selfco...

2009/11/12
We investigate the evolution of magnetic helicity density in the course of 2D and 3D kinetic magnetic reconnection through thin current sheets. In 2D, the helicity density near a reconnection X-line b...
