 +   <​hidden TTP02-15 ​ Special case of sunset: reduction and epsilon-expansion > We consider two loop sunset diagrams with two 
 + mass scales m and M at the threshold and pseudotreshold 
 + that cannot be treated by earlier published formula. 
 + The complete reduction to master integrals 
 + is given. The master integrals are evaluated as series in 
 + ratio m/M and in epsilon with the help of differential equation method. 
 + The rules of asymptotic expansion in the case when q^2 is 
 + at the (pseudo)threshold are given.
