Remnants of the Fall: Revelations of Particle Secrets
Now isotopic-spin rotations are not rotations in space or in any "internal space,"
but are instead changes of the type of particle — we envision these "rotations" in
our minds and can perform them in our mathematics. Since the mathematics is ...

A fancy way of expressing the charge independence of the strong interaction is to
say that it is invariant under rotations in isotopic spin space. What does this mean
? If a system is invariant under rotations in ordinary space, it means that it does ...

The strong interaction depends on I, not on I z : the third component of the strong
isotopic spin behaves like the electric charge. The strong isotopic spin is not
conserved in decays induced by weak and electromagnetic interactions (the
latter ...

This and the knowledge that there are three charge states of the pion, and that
pions can be coupled to the nucleon field singly, lead to the conclusion that pions
have isotopic spin unity. A direct verification of this conclusion was found in the ...

(B) Isotopic Spin Formalism In this formalism we are considering the proton and
the neuiron as different quantum states of the same particle, the nucleon. The
total wave-function is written as a product of the space part, a spin part and an ...

It can be seen that in strong interactions all symmetries hold. In weak interactions
a number of symmetries are violated. Of electromagnetic interactions, it is only
isotopic spin which is violated, but its third component (projection) is conserved.

An Elementary Primer for Gauge Theory
In the Yang-Mills theory, the phase is replaced by a more complicated local
variable that specifies the direction of the isotopic spin. In order to understand
qualitatively how this leads to a connection, we need only to recall that the SU(2)

Field Theory and Symmetry Principles
The corresponding isotopic spin operator for a nucleon is then given by (1.4) with
T representing the 2x2 Pauli matrices. The electromagnetic field is described by
the Hamiltonian Hy=-$j,A^r (1.5) where A^ is the electromagnetic potential ...
