Abstract

In this study, the spin-momentum correlation of one massive spin- $${\frac{1}{2}}$$ and spin-1 particle states, which are made based on the projection of a relativistic spin operator into timelike direction is investigated. It is shown that by using Non-Linear entanglement witnesses (NLEWs), the effect of Lorentz transformation would decrease both the amount and the region of entanglement.
