在HERA用ZEUS探测器测量光子-质子总截面的能量依赖性

Measurement of the energy dependence of the photon-proton total cross section with the ZEUS detector at HERA

Amir Stern

摘要:

光子-质子总截面的能量依赖性是根据HERA的ZEUS探测器在γp系统的三个质心能量W值(范围为194<W<296 GeV)下收集的正电子-质子散射数据确定的。这是第一次从一个单一的实验在高W的光子-质子总截面的W依赖性的测定。参数化σtot(γp)αW^(2ε),ε= 0.111 \pm 0.009(stat.)\pm 0.036(系统)得出

英文摘要:

The energy dependence of the photon-proton total cross section was determined from positron-proton scattering data collected with the ZEUS detector at HERA at three values of the center-of-mass energy, W, of the γp system in the range 194<W<296 GeV. This is the first determination of the W dependence of the photon-proton total cross section from a single experiment at high W. Parameterizing σtot(γp) αW^(2ε), ε= 0.111 \pm 0.009 (stat.) \pm 0.036 (syst.) was obtained.
