W- A HINT OF NEW PHYSICS(1 JET TO W+0 JET RATIO AT THE TEVATRON )

We interpret the reported disagreement between the measured ratio, R-1 0, of the W + 1 jet cross-section to the W + 0 jet cross-section at th e Tevatron and the Standard Model (SM) prediction, as the effect of in teractions mediated by a colour-octet analogue of the W-8. boson, the W-8. The presence of a W-8 with mass O(300) GeV, and with couplings to quarks and gluons of the order of electroweak strength, allows the ob servations of the DO collaboration to be reproduced quite accurately. The same interaction leads to an enhancement in the dijet production r ate which is well within experimental limits; in W+W- production, the enhancement is more significant and could serve as a discriminant as m ore statistics accumulate.
