B and C Quark Production Results from Dd
We describe recent results on b and c quark production from the DD collaboration. Our measurements of the inclusive b quark cross section in the central region at p s = 1.8 TeV and 0.63 TeV are compared to theoretical predictions. NLO QCD describes the p T dependence of the b cross section accurately, but underestimates its magnitude by a factor of two. In the forward rapidity region (2:4 <j y ...
متن کاملMulti - pion production in the dd → αX reaction
A simple model, based on two parallel and independent NN → dπ processes, has recently been proposed for two-pion production in the dd → αX reaction. It reproduces all observed features, including the sharp peak structure in momentum distributions (the ABC effect) and the strong oscillations in the deuteron vector and tensor analyzing powers. This model is now extended to describe also four-pion...
متن کاملViral Infections and their Role in Autoimmune Diseases, with Emphasis on Mechanisms and Molecular Interactions
Introduction: The exact cause of most autoimmune diseases is still unknown; however, several factors play a role in causing or exacerbating autoimmune reactions. In addition to environmental factors such as bacterial, parasitic, fungal and viral infections, factors such as genetic characteristics and lifestyle are also included. Infections caused by viruses usually trigger a strong immune respo...
متن کاملEffects of Kinetin, IAA, and Gibberellin on Ethylene Production, and Their Interactions in Growth of Seedlings.
Kinetin in concentrations of 10(-8) to 10(-4)m, stimulated ethylene production in 3 and 4-day old etiolated seedlings of Alaska pea (Pisum sativum L. var. Alaska). Seedlings of other species responded similarly. The response to kinetin depended on the age of the seedlings.Kinetin alone did not influence ethylene production in 6-day old stem sections, but it greatly increased the enhancing effec...
