MHV Amplitudes
In theoretical particle physics, maximally helicity violating amplitudes (MHV) are amplitudes with n massless external gauge bosons, where n-2 gauge bosons have a particular helicity and the other two have the opposite helicity. These amplitudes are called MHV amplitudes, because at tree level, they violate helicity conservation to the maximum extent possible. The tree amplitudes in which all gauge bosons have the same helicity or all but one have the same helicity vanish. MHV amplitudes may be calculated very efficiently by means of the Parke–Taylor formula. Although developed for pure gluon scattering, extensions exist for massive particles, scalars (the Higgs) and for fermions (quarks and their interactions in QCD). Parke–Taylor amplitudes Work done in 1980s by Stephen Parke and Tomasz Taylor found that when considering the scattering of many gluons, certain classes of amplitude vanish at tree level; in particular when fewer than two gluons have negative helicity (a ...

MHV Connector
The MHV (miniature high voltage) connector is a type of RF connector used for terminating coaxial cable. Description The connector looks almost identical to a typical BNC connector, but is designed to not mate with BNC jacks. It features two bayonet lugs on the female connector; mating is fully achieved with a quarter turn of the coupling nut. The dimensions of the connector are specified in the MIL-STD-348B. MHV connectors can be recognized by the slightly protruding insulation on the male plug and the slightly different insulation length in the female jack. Use The MHV connector is typically rated for 1500 VRMS continuous and 5000 V peak, and 3 amperes. With an operating frequency limited to about 300 MHz their usage is restricted to low frequency applications. It was commonly used in laboratory settings for voltages beyond the rating of BNC connectors. Other applications include: *Geiger counters *Scintillation probes *Transmission lines * High-voltage power ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mojave Air And Space Port
The Mojave Air and Space Port at Rutan Field is in Mojave, California, United States, at an elevation of . It is the first facility to be licensed in the United States for horizontal launches of reusable spacecraft, being certified as a spaceport by the Federal Aviation Administration on June 17, 2004. The facility covers 2,998 acres (1,213 ha) and has three runways. History In 1935, Kern County opened the Mojave Airport east of Mojave, California to serve the gold and silver mining industry in the area. The airport had two dirt runways, one oiled, but no fueling or servicing facilities. In 1941, the Civil Aeronautics Board began improvements to the airport for national defense purposes that included two asphalt runways and a taxiway. Kern County agreed the airport could be taken over by the military in the event of war. After the Japanese attack on Pearl Harbor in December 1941, the United States Marine Corps took over the airport and expanded it into Marine Corps A ...
