Do Mutants Have to be Slain, or Do They Die of Natural Causes?: The Case of Atomic Parity Violation Experiments
Published online by Cambridge University Press: 31 January 2023
Extract
In Constructing Quarks (1984) Andrew Pickering discussed the early experiments on atomic parity violation performed at Oxford University and at the University of Washington and published in 1976 and 1977. The results disagreed with the predictions of the Weinberg-Salam (W-S) theory of unified electroweak interactions. Another experiment, performed at the Stanford Linear Accelerator Center in 1978, on the scattering of polarized electrons from deuterons confirmed the theory. Pickering regards the Oxford and Washington experiments as mutants, slain by the SLAC experiment.
By 1979 the W-S theory was regarded by the high-energy physics community as established, despite the fact that as Pickering recounts, “there had been no intrinsic change [emphasis in original] in the status of the Washington-Oxford experiments.” (Pickering 1984, p. 301).
