Intrinsic Parity of the (j,0)(0,j) Mesons
Abstract
Contrary to the usual belief, by carefully examining the operation of parity transformation on the (1,0)(0,1) mesons in the generalized canonical representation, we establish that the (j,0)(0,j) meson-antimeson pair have opposite intrinsic parity. This opens up the possibility that while the particles without an internal structure may utilize one representation of the Lorentz group, phenomenologies of composite particles may exploit a different representation. As such (perhaps, only some of) the meson structures beyond the standard q\, Q may exploit the (j,0)(0,j) generalized canonical representation of the Lorentz group -- this would result in a meson and the associated antimeson to manifest themselves in different partial waves. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% CONSTRUCTIVE COMMENTS WELCOME, AS ALWAYS D.
