Biography/History:

Richard Talman is Professor Emeritus in the Department of Physics, Cornell University. He received his PhD in 1963 from the California Institute of Technology. His recent efforts have been devoted to planning for a new generation of accelerators following the LHC p,p collider at CERN He has also been developing a method for measuring the electric dipole moments (EDM) of the electron and proton. His multiple visiting appointments include Stanford, CERN, UC Berkeley, University of Chicago, University of Texas at Austin, Duke, and many more.

Summary:

The electric dipole moment (EDM) challenge measures a non-zero proton EDM value and this book suggests how the challenge can be met. Any measurably large proton EDM would violate the standard model. The method to be employed uses an intense beam of 'frozen spin' protons circulating for hour-long times in a storage ring 'trap'. The smallness of EDMs allows them to test existing theories, but also makes them hard to measure. Such EDM experiments are inexpensive, at least compared to building accelerators of ever-greater energy.
