“A General Separation of Colored and White”: the WWII riots, military segregation, and racism(s) beyond the White/Nonwhite binary

This article uses archival research to explore important differences in the discursive and institutional positioning of Mexican American and African American men during World War II. Through the focal point of the riots which erupted in Los Angeles and other major cities in the summer of 1943, I examine the ways in which black and Mexican ‘rioters’ were imagined in official and popular discourses. Though both groups of youth were often constructed as deviant and subversive, there were also divergences in the ways in which their supposed racial difference was discursively configured. I also consider the experiences of each group in the WWII military, a subject that has received little attention in previous work on the riots. Though both groups were subject to discrimination and brutality on the home front, only African Americans were segregated in the military - a fact that profoundly influenced the 1943 riots. Examining the very different conditions under which these men served, as well as the distinct ways in which their presence within the military and on the home front was interpreted and given meaning by press, law enforcement and military officials helps to illuminate the uneven and complex workings of racism in America, disrupting the common conceptualization of a definitive white/nonwhite color line

Multiplicity Difference between Heavy and Light Quark Jets Revisited

The perturbative QCD approach to multiparticle production predicts a characteristic suppression of particle multiplicity in a heavy quark jet as compared to a light quark jet. In the Modified Leading Logarithmic Approximation (MLLA) the multiplicity difference \delta_{Q\ell} between heavy and light quark jets is derived in terms of a few other experimentally measured quantities. The earlier prediction for b-quarks needs revision in the light of new experimental results and the improvement in the understanding of the experimental data. We now find \delta_{b\ell}=4.4\pm0.4. The updated MLLA results on \delta_{b\ell} and \delta_{c\ell} are compared with the present data from e^+e^- annihilation. Their expected energy independence is confirmed within the energy range between 29 and 200 GeV; the absolute values are now in better agreement with experiment than in the previous analysis, and the remaining difference can be attributed largely to next-to-MLLA contributions, an important subset of which are identified and evaluated.Comment: 33 pages, 2 figures, version to appear in Eur.Phys.J.
