Extracting parameters from supersymmetric heavy Higgs bosons
It has been hoped that the processes e+e−→bbH and bbA within supersymmetry could be used to measure the b-quark Yukawa coupling and thus tan β when it is large. However, 1-loop threshold corrections can change by O(1) the relationship between yb and mb, making a clean extraction of tan β more difficult but presenting other opportunities to probe and constrain high-scale physics. In particular, SO(10)-like grand unified theories typically predict a cross-section roughly two times larger than predicted at tree-level when running at s
