在DIS中首次观察到(反)氘核

First observation of (anti)deuterons in DIS

S. Chekanov

摘要:

本文报道了在HERA用ZEUS探测器首次观测到的深非弹性散射中的(反)氘核。氘核的产生率高于反氘核。然而,质子和反质子的产生率并不存在不对称性,(反)氘核产额比(反)质子产额约小3个数量级,这与国际上的测量结果是一致的。

英文摘要:

First observation of (anti)deuterons in deep inelastic ep scattering (DIS) measured with the ZEUS detector at HERA is reported. The production rate of deuterons is higher than that of antideuterons. However, no asymmetry in the production rate of protons and antiprotons was found. The (anti)deuteron yield is approximately three orders of magnitude smaller than that of (anti)protons, which is consistent with the world measurements.
