A Chain of Mistakes in Theoretical Physics : July 2023　: 　

In this short note, I should like to briefly describe a chain of mistakes in theoretical physics. First, I begin with discussing the anomaly problem which is proposed by Adler, and then clarify there should be no physical meaning in the Einstein equation. Further, the problem of Feynman propagator is explained why it should not be applied to the loop diagrams, and the problem of Dimensional Regularization by 't Hooft and Veltmann is also clarified. In addition, the intrinsic defect of Weinberg-Salam model is clarified in connection with the non-abelian nature of gauge fields. Finally, I should make a brief comment on the confinement of quarks and gluons since people misunderstood the confinement of quarks as the dynamical effects. In reality, the confinement of quarks should be due to the kinematical effects in that the color charges of quarks are not physical observables.
This short note should be considered to be some solutions and answers of corresponding physics problems which are discussed in the textbooks, [ Symmetry and Its Breaking in Quantum Field Theory (Nova Science Publishers, 2011) and [ Fundamental Problems in Quantum Field Theory ( Bentham Publishers, 2013) ].
