## Two Jet Kinematics

At the LHC, partons in the incoming beams (beam energy =7 TeV) collide with a momementum fraction and produce two jets with negligible mass, transverse momentum and rapidities .

Show that

#### 2.

Show that the invariant mass of the jet-jet system is

and the centre-of-mass scattering angle is given by

#### 3.

Discuss the regions of and that can be studied at the LHC with a jet trigger of GeV and .

#### 4.

Use MadGraph/MadEvent to obtain the relative contribution of initial states to the jet distribution as function of the at the Tevatron Run II ( collisions at 1.96 TeV) and the LHC ( collisions at 14 TeV).
