Conclusions Drummond, Henn, ● Evidence for exponentiation - DCI?? Korchemsky, Sokatchev, arXiv:0712.1223 ● Not clear from strong coupling ● Compared to N=4: ➔ Odd loops: disappear from exponent ➔ Even loops similar to N=4 SYM  Would need 4 loops to see if recurrence is satisfied with 2 loop result
