Physicists give the name “prompt photons” to those that are produced by two particles smashing together — hard collisions — as contrasted with those resulting from the decay of other particles. The Tevatron produced prompt photons by the hard collisions between protons and antiprotons.
Former Fermilab Deputy Director Young-Kee Kim was once a CDF experiment postdoc who put her heart and soul into the particle detector. At one point, her tireless efforts brought her work to a brief, soporific standstill.
The hunt for the top quark at Fermilab was heating up in 1994 when scientist Mike Albrow and his colleagues on the CDF experiment felt they were close to cornering the last, undiscovered member of the quark family. Albrow tells the story leading to the discovery of the particle by CDF and DZero.
One of the stalwarts of the Tevatron Collider era, Giorgio Bellettini will give a colloquium on the history of the CDF experiment and the contributions of Italian physicists to CDF’s extremely successful scientific adventure.
Good news: there is a theory to describe the strong interaction, the interactions that bind the constituents of protons and neutrons together and create the strong force. Bad news: Calculations using the theory can be made in only a limited selection of natural phenomena.
