“…This relation provides much more restrictive bounds on sigma /sub h/ than the simple unitarity bounds, for the case in which the hadronic channels dominate the total annihilation cross-section. (3 refs).…”

“…The energy dependence of the total annihilation cross- section, parametrized in the form sigma (e/sup +/e/sup -/ to hadrons) =A.s/sup n/, is measured to be n=-(1.54/sub -0.29//sup +0.17/) in the above energy range. (11 refs).…”

“…We calculate the total annihilation rates, the fractions of annihilations into different Standard Model final states and the resulting fluxes of gamma rays for CMSSM scenarios along these strips. …”

“…For typical velocities during freeze-out, we find that including Sommerfeld corrections on the next-to-leading order partial wave leads to modifications of up to 10 to 20 percent on the total annihilation cross section. Complementary to QCD, we generalize our results to particles charged under an arbitrary unbroken SU(N) gauge group, as encountered in dark glueball models. …”
