Description:
Electron-proton collisions. LEPTO 6.5 with ARIADNE 4.12. Q2>1 GeV2. Min W2 was set to 4 GeV2, and the minimum energy of scattered electron was set to 0.3 GeV. MSTW2008lo68cl PDF (LHAPDF= 21000) is used. 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 detector studies.

Note that all exclusive processes were removed, therefore, this sample is not realistic for physics.

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
