A Remarkable Relation in the Gauge Sector of Electroweakdynamics
arXiv:hep-ph/0301139 · doi:10.1063/1.1594333
Abstract
A precise empirical relation between the electromagnetic coupling alpha(m_Z) and sin^2(theta^ell_{eff}) --where theta^ell_{eff} is the effective electroweak mixing angle extracted from Z leptonic decays-- is made manifest: alpha(m_Z) = sin^3(theta^ell_{eff})*cos(theta^\ell_{eff}}/(4π}.
