Query: Exclusive heavy quark dijet cross section   We study the exclusive heavy quark dijet cross section from
$e^+e^-$-annihilation using soft-collinear effective theory. In order to resum
the large logarithms of small jet veto parameter $\beta$ and jet radius $R$, we
factorize the cross section into the hard, hard-soft, collinear, and
collinear-soft parts. Compared with the case of a massless quark, the jet
sector with the collinear and collinear-soft parts can be modified to include
the heavy quark mass. The factorization of the jet sector can be systematically
achieved through matching onto the boosted heavy quark effective theory. Heavy
quark mass corrections enhance the cross section sizably and cannot be ignored
when the quark mass is comparable with the jet size $E_JR$. We also analyze the
exclusive heavy quark pair production in the limit as $R$ goes to zero. Using
the resummed result, the top isolation effects on the cross section are
estimated.
