Description:
Electron-proton collisions. LEPTO 6.5 with PYTHIA 5.7. Q2>1000 GeV2. CTEQ 6.1L PDF. Collision energy: E(p)=250 GeV and E(e-)=20 GeV. The data sample corresponds to a simulation of high-Q2 regions at future Electron Ion Collider (EIL).

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
