Departure from Weinberg-Salam model and grandunification
Conference

OSTI ID:6635098
The spontaneous breaking of grandunified groups like SO(10) or SU(8) x SU(8) can lead to an extra U(1) group beyond Weinberg-Salam (W-S) SU(2) x U(1). Neutral current data are now shown to depend on two more parameters. The data are examined and limits are put on the mass of the extra Z boson. Need for more experiments on parity violation effects in atoms is stressed. 2 figures, 1 table.
