Description

A new factorization theorem for the precision extraction of the top mass from top pair production far above threshold at the ILC is presented. The factorization theorem gives a precise relation between the measurement of properties of top jet distributions, such as thrust or hemisphere invariant mass, and the top mass. The observable is shown to be sensitive to a new class of top mass schemes called `top resonance' schemes which can be converted to the well known MS top mass schemes. The factorization theorem sums large logarithms involving the center of mass energy, the top mass, and the top width via renormalization group equations in a sequence of effective field theories. NLL resummed results are presented.
