Isospin and generalized Pauli principle Isospin, ˆt, operator of isospin, has all the
mathematical properties of the spin operator ˆs =ˆσ/2 (in units of ~), ˆt=(ˆtx,ˆty,ˆtz),
ˆt = ˆτ/2, t = 1/2, mt =±1/2. Proton and neutron may be considered to be two ...

Introduction to Elementary Particle Physics
The two initial hadrons belong to two isospin multiplets, and similarly the final
ones. Changing the particles in each of these multiplets we have different
reactions, with cross-sections related by isospin conservation. We shall see some
...

Symmetry Principles Particle Physics
APPENDIX C ISOSPIN AND SU(3) PHASE CONVENTIONS This appendix
contains an explanation of the phase conventions used in this book for the
operators and states of the internal symmetries: isospin, SU(3) and charge
conjugation.

But abstract as it is, the isospin concept, extended and combined with Gell-
Mann's strangeness rules, displays just what theorists want to know: the
underlying symmetries of the nucleon and its hadron relatives. We will need a
few more items ...

Lie Groups for Pedestrians
Selection rules. One can also find selection rules which result from isospin. For
example, if one considers only nucleons and pions, states having an odd baryon
number must belong in a multiplet with a half-integral isospin, whereas states
with ...

Concepts of Particle Physics
(a) Weak isospin An analysis of these undesirable features (see §§VI.A and B,
Vol. II) reveals that they stem from a lack of symmetry of the charge-changing
weak interaction. These symmetry features of weak processes can be understood
by ...

Australian Lonergan Workshop
isospin is a direct consequence of the charge independence of hadronic forces.
The proton and neutron, for example, can be treated as two states of the same
particle, the nucleon. Without the electromagnetic interaction the particles would
...
