Entanglement and maximal violation of the CHSH inequality in a system of two spins j: A novel construction and further observations

We study the CHSH inequality for a system of two spin j particles, generic j. The operator is constructed using set unitary, Hermitian operators {A1,A2,B1,B2}. expectation value analyzed singlet state |ψs〉. Being |ψs〉 an entangled state, violation compatible with Tsirelson's bound found. Although construction employed here differs from that [1], full agreement recovered.
