Pairs-Production of Higgs in Association with Bottom Quarks Pairs at Colliders
In a previous paper, we studied the Higgs pair production in the standard
model with the reaction . Based on this, we study
the Higgs pair production via . We evaluate the
total cross section of and calculate the number total of events
considering the complete set of Feynman diagrams at tree-level, and compare
this process with the process . The numerical
computation is done for the energy which is expected to be available at a
possible Next Linear Collider with a center-of-mass energy and luminosity 1000 .Comment: 12 pages, 6 figure
Effect of cooling rate during solidification on the hard phases of M23C6-type of cast CoCrMo alloy
Microstructural morphology of CoCrMo alloy by control of the cooling rate during the solidification was investigated. Samples were obtained using both an induction furnace for slow cooling rate and electric arc furnace for fast cooling rate. Microstructural characterizations were performed with metallographic techniques. It was found that the difference between the formation temperature of hard secondary phases of M23C6-type carbides determine the reduction of carbide size by increasing the cooling rate
