Scalar form factors of light mesons September 18 , 2004

The scalar radius of the pion plays an important role in χPT, because it is related to one of the basic effective coupling constants, viz. the one which controls the quark mass dependence of F π at one loop. In a recent paper, Ynduráin derives a robust lower bound for this radius, which disagrees with earlier determinations. We show that such a bound does not exist: the " derivation " relies on...

We now begin the definition and construction of Runge-Kutta methods. These one–step methods are essentially always stable, but designing Runge– Kutta methods which are consistent to high order can be difficult. This theory is presented in Sec. We have already seen several examples of Runge–Kutta methods: explicit and implicit Euler, the implicit midpoint rule, the explicit midpoint rule with Eu...

The population prevalence of intellectual disability (also known as learning disability in UK health services) is approximately 1%, rather similar to the estimate of lifetime population risk for schizophrenia. The risk of psychiatric illness, particularly schizophrenia, is thought to be increased in people with intellectual disability. Morgan et al (pp. 364–372) linked two large population-base...
