Chad J. Johnson
Encyclopedia
Chad Jeremy Johnson is an American particle physicist and noted photographer. He is best known for his work in the search for a neutral long-lived particle produced in decays of Higgs Boson
. His work was primarily at the Fermilab Tevatron
Collider in Batavia Illinois, from 2002 to 2008.
. His undergraduate physics training was at the University of Minnesota
, Twin City Campus. His work has been published in the American Physical Society Journal. http://prl.aps.org/abstract/PRL/v103/i6/e061801
; specifically in collisions that decay to b-jets and the particle that lives long enough to travel at least 1.6 cm before decaying into heavy quarks. The Higgs Boson
is the only Standard Model
of particle physics
predicted to exist that has not been observed.
Johnson’s novel search for the unnamed particle is theorized to arise in the “hidden valley” sector of particle physics. Johnson’s work involved mapping center-of-mass energy of 1.96TeV. Johnson worked with the DØ experiment, located at one of the interaction regions, where proton and antiproton beams intersect, on the Tevatron synchrotron ring, labeled 'DØ'.
His recent work is in medical physics, in the radiation oncology department centered at Columbia Presbyterian Hospital. He is developing new technologies to improve the effectiveness of lasers to target and eradicate cancerous tissue.

Particle physics
Particle physics is a branch of physics that studies the existence and interactions of particles that are the constituents of what is usually referred to as matter or radiation. In current understanding, particles are excitations of quantum fields and interact following their dynamics...
