Laser light is a convenient way of transporting both electric and magnetic fields.
Now the scattering of intense light from fast free electrons helps to establish an era of relativistic nonlinear optics, one goal being the generation of coherent x rays. As the hypothetical particle which supposedly endows other particles with mass, the Higgs is an important ingredient in the standard model of particle interactions and one of the chief quarries at present and future accelerators. At a recent meeting at Fermilab on Higgs prospects in the next round of work at the Tevatron, experimentalists were heartened by the new estimates since naturally they would like to explore as large a Higgs window as possible.
