+// Short description: If partons from the G4QPartonPair are close in
+// rapidity, they create Quasmons, but if they are far in the rapidity
+// space, they can not interact directly. Say the bottom parton (quark)
+// has rapidity 0, and the top parton (antiquark) has rapidity 8, then
+// the top quark splits in two by radiating gluon, and each part has
+// rapidity 4, then the gluon splits in quark-antiquark pair (rapidity
+// 2 each), and then the quark gadiates anothe gluon and reachs rapidity
+// 1. Now it can interact with the bottom antiquark, creating a Quasmon
+// or a hadron. The intermediate partons is the string ladder.
