N ov 1 99 8 1 Precise strength of the π NN coupling constant

چکیده
We report here a preliminary value for the πNN coupling constant deduced from the GMO sumrule for forward πN scattering. As in our previous determination from np backward differential scattering cross sections we give a critical discussion of the analysis with careful attention not only to the statistical, but also to the systematic uncertainties. Our preliminary evaluation gives g c (GMO) = 13.99(24).

We critically evaluate the isovector GMO sumrule for the charged πNN coupling constant using recent precision data from π − p and π − d atoms and with careful attention to systematic errors. From the π − d scattering length we deduce the pion-proton scattering lengths

We consider the N-body problem in (1 + 1) dimensional lineal gravity. For 2 point masses (N = 2) we obtain an exact solution for the relativistic motion. In the equal mass case we obtain an explicit expression for their proper separation as a function of their mutual proper time. Our solution gives the exact Hamiltonian to infinite order in the gravitational coupling constant.

In an effective theory containing only quark degrees of freedom, such as the extended Nambu–Jona–Lasinio model, the influence of the axial anomaly can be incorporated by a self-interaction of the 't Hooft determinant type. I will show that this leads to a significant suppression of the η ′ coupling g η ′ qq to dynamical quarks which suggests a suppression of the η ′ NN vertex as compared to the...

We consider the problem where π is an unknown permutation on {0, 1, . . . , 2n− 1}, y0 ∈ {0, 1, . . . , 2n − 1}, and the goal is to determine the minimum r > 0 such that π (y0) = y0. Information about π is available only via queries that yield π x(y) from any x ∈ {0, 1, . . . , 2m − 1} and y ∈ {0, 1, . . . , 2n − 1} (where m is polynomial in n). The main resource under consideration is the numb...
