The Predictive Power of Effective Field Theory in NN Scattering: ^3S_1-^3D_1 Mixing at Next-to Next-to Leading Order
Thomas D. Cohen, James M. Hansen
The convergence of the Q expansion in the ^3S_1-^3D_1 mixing angle is investigated through the renormalization condition used to fit the free paramteter encountered at NNLO. Althou…
Enhanced Signatures for Disoriented Chiral Condensates
Chi-Keung Chow, Thomas D. Cohen
The probability distribution in , the proportion of neutral pions to all pions emitted in heavy ion collisions in certain kinematic regions, has been suggested as a signal of a…
Perturbative Pions and the Effective Range Expansion
Thomas D. Cohen
In this talk the counting scheme to implement effective field theory is discussed. It is pointed out that there are two small mass scales in the problem and with $1…
Signatures of Disoriented Chiral Condensates from Charged Pions
Thomas D. Cohen, Chi-Keung Chow
We show that the variance in the number of charged pions (in a suitable range of momentum space) provides a signature for the observation of a disoriented chiral condensate (DC)…
