The ππ S - wave scattering lengths July 11 , 2000

We match the known chiral perturbation theory representation of the ππ scattering amplitude to two loops with a phenomenological description that relies on the Roy equations. On this basis, the corrections to Wein-berg's low energy theorems for the S-wave scattering lengths are worked out to second order in the expansion in powers of the quark masses. The resulting predictions, a 0 0 = 0.220 ± ...

"Normally, when you eat a high-fat meal, you end up with high levels of triglycerides, a type of fat, in your blood," said Sheila West, associate professor of biobehavioral health, Penn State, who led the study. "If this happens too frequently, or if triglyceride levels are raised too much, your risk of heart disease is increased. We found that adding spices to a high-fat meal reduced triglycer...

It is expected that the final Real Estate Settlement Procedures Act rule will encourage shopping, increase efficiency, lower housing costs, and promote the purchase of loans that are more suited to a household’s needs. The transfer of markups from firms charging excessive fees to consumers has been estimated to be approximately $670 per loan (a total of $8.35 billion) but could be as high as $1...
