Description:
Electron-proton collisions. LEPTO 6.5 with ARIADNE 4.12. Q2>1 GeV2. MSTW2008lo68cl PDF (LHAPDF= 21000). Other default parameters are E(scattered)>1 GeV and W2>5 GeV2. Collision energy: E(p)=60 GeV and E(e-)=5 GeV. These energies are designed for the JLab EIC proposal. The samples were requested by J.Repond for ANL LDRD studies.

Comment

Event Q2, W, X and Y are encoded as
        eve->set_scale(W)
        eve->set_alpha_qed(y)
        eve->set_alpha_qcd(x)
        eve->set_scale_pdf(q2)
        eve->set_x1(x)
        eve->set_x2(y)
Starting from the tag rfull054, truth-level event variables are included in the LCIO files as "parameters" with the keys:
 parameter EVGEN:eCM [float]
 parameter EVGEN:Process [string]
 parameter EVGEN:ID1 [int]
 parameter EVGEN:ID2 [int] 
 parameter EVGEN:ProcessID [int]
 parameter EVGEN:DIS:Q2 [float]      // Truth-level Q^2
 parameter EVGEN:DIS:W [float]       // Truth-level W
 parameter EVGEN:DIS:XBJ [float]     // Truth_level x_bjorken
 parameter EVGEN:DIS:YBJ [float]     // Truth_level y_bjorken
