Thus the connected unimodular branch is lambda det(m)=1. No charge 000058 | fit is used: normalize its U(1) using the original P2 Y above and put 000059 | lambda=exp(i t/2), m=exp(-i t/6) conjugate(U3), q in SU(2). 000060 | The physical color matrix U3 is the conjugate of the raw determinant-one 000061 | part of m because the particle color action comes from J_F pi(u) J_F^-1. 000062 | 000063 | Multiplying the actual blocks gives 000064 | particle Q_L: exp(+i t/6) (U3 tensor q), 000065 | particle L_L: exp(-i t/2) q, 000066 | antiparticle u_R^c: exp(-2i t/3) conjugate(U3), 000067 | antiparticle d_R^c: exp(+i t/3) conjugate(U3), 000068 | antiparticle e_R^c: exp(+i t), 000069 | antiparticle nu_R^c: 1. 000070 | These are exactly the gamma_F=+1 slots. The dimensions are 6,2,3,3,1,1, 000071 | and the complete hypercharge multiset is 000072 | (1/6)^6, (-1/2)^2, (-2/3)^3, (1/3)^3, (1)^1, (0)^1. 000073 | This verifies SU(3), SU(2) and hypercharge together, not just the multiset.
