我们研究了平方根s = 1.8 TeV下质子-反质子碰撞中的单衍射离解（ppBAR—> pXBAR），范围3小于或类似于M(X)小于或类似于200 GeV， 0.05小于或类似于t的绝对值小于或类似于0.11 (GeV/c)2。参数化生产的形式为dsigma/(dtdM(X)2) = (M(X)2)-alpha exp(bt)，我们得到alpha = 1.13 +/- 0.07和b = 10.5 +/- 1.8 (GeV/c)-2。总单衍射解离截面为2sigma(SD) = 8.1 +/- 1.7 mb。与之前较低能量的数据进行了比较。和我们之前在相同能量下的测量。
We have studied single diffraction dissociation (ppBAR --> pXBAR) in proton-antiproton collisions at square-root s = 1.8 TeV, covering the ranges 3 less than or similar to M(X) less than or similar to 200 GeV and 0.05 less than or similar to Absolute value of t less than or similar to 0.11 (GeV/c)2. Parameterizing the production to be of the form dsigma/(dtdM(X)2) = (M(X)2)-alpha exp(bt), we obtain alpha = 1.13 +/- 0.07 and b = 10.5 +/- 1.8 (GeV/c)-2. The total single diffraction dissociation cross section is 2sigma(SD) = 8.1 +/- 1.7 mb. Comparisons are made to previous lower energy data. and to an earlier measurement by us at the same energy.
