Relativistic field theory,covariance, that guarantees the invariance of the equations of motion under changes of reference frame, and of the principle of causality, which is connected to the principle of locality, namely, the independence of variables associated to different points in space at the same time.Glutinous 发表于 2025-3-27 05:36:29
Spinor fields,th in Chapters 7 and 8) is provided by vector fields: . In the general case, we have a system of complex fields ., . = 1, ..., ., with the transformation law . where the matrix . obeys the condition . for any two Lorentz transformations .. The vector field is an obvious example; in that case, we have simply . ≡ .).没花的是打扰 发表于 2025-3-27 13:14:16

Gauge symmetries, where ., . are real constants. Notice that we have inserted a Dirac mass term, which is allowed by the assumed invariance properties, while Majorana mass terms are not, as mentioned in Section 5.2. The conserved current is given by . and the constant e plays the role of elementary charge.epicardium 发表于 2025-3-28 06:16:39

https://doi.org/10.1007/978-3-322-83371-6the interaction in eq. (7.1) is non-renormalizable, since it contains operators with mass dimension 6; it is an effective theory, in the sense that it can only be used to compute amplitudes in the semi-classical approximation.
