 +  
 +   <hidden TTP08-11  Ultrasoft contribution to heavy quark pair production near threshold > We compute the third-order correction to the heavy-quark current correlation function due to th 
 + e emission and absorption of an ultrasoft gluon. Our result supplies a missing contribution to 
 + top-quark pair production near threshold and the determination of the bottom quark mass from QC 
 + D sum rules.
