BH
The main goal of this work is to estimate effects of the other diagrams than
2- BH.
Here 3 examples are presented for this purpose.
In all cases, the beam energies are 27.5GeV for the positron and 820GeV for the proton.
The label EW denotes results of a calculation including all the diagrams
in Fig.1 or 2.
