cross section
We calculate the cross section for the dissociation of J/ψ by kaons within the framework of a meson exchange model. We find that, depending on the values of the coupling constants used, the cross section can vary from 5 mb to 30 mb at √ s ∼ 5 GeV. In relativistic heavy ion collisions J/ψ suppression has been recognized as an important tool to identify the possible phase transition to quark-gluo...
متن کاملIce Cores , High - Mountain Glaciers , and Climate
The near-global retreat of high-mountain glaciers and the shrinkage of ice fields and ice caps and retreat of their associated outlet glaciers are perhaps the most visible evidence for 20th-century climate change and the recent increase in the globally averaged near-surface temperatures of the Earth’s surface. The loss of high-mountain glaciers—including ice fields, ice caps, and other glaciers...
متن کاملExpanding mountain forest promotes climate warming
Environment[1] Environment[1]Climate Change [2]Forest [3]Mountain [4]Norway [5]Forskning.no [6] Birch forest is currently expanding in mountain regions because of climate warming and reduced grazing pressure. A recent study shows that increased mountain forest promotes climate warming. Tourists and locals have noticed that forests are creeping up hillsides in mountain regions in Norway. Beautif...
متن کاملThe mountain environment, a driver for adaptation to climate change
The mountain environment is perceived today by vine-growers as a strong structural constraint. Yet in the current context of climate change, in which we turn to genetics, irrigation or innovation in cultural practices to maintain production quality, could the mountain environment emerge as a solution for adapting to climate change in vine-growing? Here we explore the role of cooperative policie...
متن کاملSimulation of Convective Heat Transfer of a Nanofluid in a Circular Cross-section
The CFD simulation of heat transfer characteristics of a nanofluid ina circular tube under convective heat transferwas considered using the fluentsoftware (version 6.3.26) in the laminar flow. Al2O3nano- particles in water with concentrations of 0.5, 1.0, 1.5, 2 and 2.5% were studied in the simulation. All thermo-physical properties of nanofluids were temperature independent. It was concluded t...
