Neutrino, parity violation, V-A: a historical survey

Good historical detail on the importance of the reversal of the RR experiment to the development of VA theory, the key step on the road to the standard model.
This is a concise story of the rise of the four fermion theory of the universal weak interaction and its experimental confirmation, with a special emphasis on the problems related to parity violation.
V-A was in a very good agreement with most of the experiments but its authors had to make the bold assumption that the predictions of the rest were actually erroneous; needless to say, this required a thorough work. Sudarshan and Marshak [SM1] concluded: ”While it is clear that a mixture of vector and axial vector is the only universal four-fermion interaction which is possible and possesses many elegant features, it appears that one published [RR53] 25 and several unpublished experiments cannot be reconciled with this hypothesis... All of these experiments should be redone... If any of the above four experiments stands, it will be necessary to abandon the hypothesis of a universal V+A four-fermion interaction...” 26 .
In their review [G-MR] published in December 1957 (the survey of literature pertaining to the review being completed in July, 1957) Gell-Mann and Rosenfeld made the following comment: ”... there has been speculation that the form of the interaction might also be ’universal’. Such a situation seems to be ruled out if the β -decay coupling is primarily S and T and the µ decay coupling V and A... Since the β -decay picture is somewhat confused at the moment, let us discuss briefly the possibility that we may have V and A there too, instead of S and T with a possible admixture of V. We may call this V, A hypothesis the ’last stand’ of the UFI... We must first of all disregard much of the evidence on27 e − ν angular correlation in β -decay, especially the result of Rustad & Ruby on He 6 , which clearly indicates T rather than A. This is already a very serious objection to the UFI.”
Discussing the universality of the weak interaction with V-A in [FG-M], Feynman and Gell-Mann also stressed that ”... At the present time several β -decay experiments seem to be in disagreement with one another. Limiting ourselves to those that are well established, we find that the most serious disagreement with our theory is the recoil experiment in He 6 of Rustad and Ruby 28 indicating that the T interaction is more likely than the A. Further check on this is obviously very desirable.” Feynman’s picturesque story in [FL, Me] about experimental points at the edge of the data range reflects his personal battle with this problem.
On the Electron-Neutrino Angular Correlation

Early paper by Morita cites Rustad-Ruby results one month after publication.
The electron-neutrino angular correlation functions are calculated for the allowed and first forbidden transitions in the Fermi theory of beta decay taking into account the effect of the nuclear charge. The interferences which arise due to squaring of terms in the interaction are worked out perfectly. The Majorana theory is also handled for the allowed transition. The differences observed between both theories are not so serious. The experimental data are consistent with the tensor interaction.
We assume that the transition is allowed because of the experimental spectrum. And as in the present situation the experiment is very difficult, it is seemed that the sign of cos θ is only probable. In allowed transition T and V which have the positive sign of cos θ are drawn with arbitrary normalization (two curves per .each type and each energy) in Figs. 3 and 4. According above considerations the curves are well fit to the experimental data. It is correct that S32 has spin 0, and P32 has spin 1 probably, so that the interaction of β-decay is tensor. But if P32 has spin 0 it is vector. .Recently it is indicated that tensor is preferable in the case of He6.

Execution of Julius and Ethel Rosenberg
The clemency campaign to spare a Jewish-American couple convicted of espionage failed to prevent their execution at Sing Sing prison on June 19, 1953. The Rosenbergs were the only two American civilians to be executed for espionage-related activity during the Cold War. Stan considered the prosecution of the Rosenbergs as the height of McCarthy Era hysteria.
