This gives a theoretically precise method for determining the CP violating phase gamma by fitting to the B-> pi pi data without C_{pi0 pi0}. SCET predicts that gamma lies close to the isospin bounds. With the current world averages we find gamma=75^o \\pm 2^o {}^{+9^o}_{-13^o}, where the uncertainties are theoretical, then experimental.","authors_text":"Christian W. Bauer, Iain W. Stewart, Ira Z.
