A top quark with mt ∼ 175 GeV is produced at rest in a collider. What is the maximum transverse (with respect to the beam axis) momentum that the b quark can have immediately after the decay of the t quark? (mW ∼ 80 GeV, assume the b is massless)
) Despite its large mass, explain why top quarks are predominantly produced in tt¯ pairs (rather than singly) in a proton-proton collider
Consider the decay of a charged pion, π + → µ + νµ. (a) Draw the Feynman diagram for this decay, labelling clearly all particles and vertex strengths.
