Pauli encloses a letter to Springer. He talks about a new paper by Schwinger on elementary particles. He writes on the logical connection of Källén's recent results to an example given by Jost last spring. He also talks about Thirring's model.
Zonder titelPauli's remarks on a preliminary paper by Misner on a Hamiltonian principle for quantized covariant field theory. misner_0399-4. For a better quality image of the appendix, see misner_0399-4.
Zonder titelPauli replies to Heisenberg's letter of the 30 October, on $\gamma$-invariance and conservation of electric charge: which group corresponds to this? He talks about mirror-invariance in isotopic spin space.
Zonder titelPauli writes about his interest in Touschek's remark at Padova and Venice about the derivation of C- and P-symmetry from special properties.
Zonder titelPauli makes critical comments on Fierz's last letter and his calculations. He writes on speculations about C-, P-, T-invariance. Possibly it is not the strength of the interaction but primarily its form which determines C-, P-, T-invariance.
Zonder titelFierz writes on further calculations concerning fields with spin. He makes some remarks on Heisenberg's treatment of the Lee-model.
Zonder titelPauli makes remarks on Misner's work: the Hamiltonian density cannot vanish, neither classically nor with quantization.
Zonder titelFierz gives a schematic description of the parity experiments. He makes theoretical comments on the Lee model.
Zonder titelPauli is against Heisenberg's approach to quantum electrodynamics. It is impossible to work only with energy-momentum values and the S-matrix and to disregard space and time. He talks about some clarifications on his own last letter but one. He writes on the separation of purely mathematical quantities from physically significant ones.
Zonder titelPauli replies to Lüders' letters of 8 Dec and 13 Dec about elementary particle theory.
