... • In the diagrams below there is an axis of rotation perpendicular to the page that intersects the page at point O. Figure (a) shows particles 1 and 2 moving around point O in opposite rotational directions, in circles with radii 2 m and 4 m. Figure (b) shows particles 3 and 4 traveling in the same ...

Flavour symmetry -- 50 years after SU(3)
... The name isospin was introduced by Eugen Wigner in 1937. Isospin is mathematically described by the SU(2) group (analogously to spin). The strength of the strong interaction between any pair of nucleons is the same, independent of whether they are interacting as protons or as neutrons. ...

INTRINSIC SYMMETRIES
... In this case the periodical behavior, with respect to the elements of the group , can be seen in both: eigenenergies and projection operators. Searching for these kinds of symmetries is not easy. In a natural way, it can be done only in the last case because in this case we do not need to decompose ...
