ELECTROWEAK ASYMMETRY OF D * AND D MESONS PRODUCED IN e÷e - A N N I H I L A T I O N S AT 29 GeV

چکیده
The production of D* and D mesons has been studied in e+e annihilations at x/~=29 GeV. The data, corresponding to an integrated luminosity of 300 pb~, were obtained using the HRS detector at PEP. The cross section is measured to be R (D o + D + ) = 2.40 + 0.35 and we determine the electroweak asymmetry to be 9.9 + 2.7%, which corresponds to an axial vector coupling constant product g~gC = 0.26 + 0.07.

متن کاملσ-sporadic prime ideals and superficial elements
Let $A$ be a Noetherian ring, $I$ be an ideal of $A$ and $sigma$ be a semi-prime operation, different from the identity map on the set of all ideals of $A$. Results of Essan proved that the sets of associated prime ideals of $sigma(I^n)$, which denoted by $Ass(A/sigma(I^n))$, stabilize to $A_{sigma}(I)$. We give some properties of the sets $S^{sigma}_{n}(I)=Ass(A/sigma(I^n))setminus A_{sigma}(I...
