Consider the reaction e + + e - q + q at a collider with CM

Question:

Consider the reaction e⁺ + e^- → q + q̅ at a collider with CM energy √s = 20 GeV. Give a typical value of the hadronic jet opening angle in a two-jet event. If θ is the angle of the common jet direction with the beams, what is the ratio between the counting rates at θ = 90° and θ = 30°?
