摘要：
The antiproton production cross-section in p-He collisions at root sNN = 110 GeV is measured with the LHCb experiment at CERN. The results are important. for the interpretation of the data collected by the space-borne experiments PAMELA and AMS for the antiproton fraction in cosmic rays. The potential of an indirect observation of dark matter is presently limited by the uncertainty on the antiproton production in interactions between cosmic rays and the interstellar medium.
