"However," he added, "there is one problem that the standard model does not explain." "This theory explains almost everything we know about the universe up to this point," said Van Kolck.
Developed by Van Kolck's former doctoral advisor, Nobel Laureate Steven Weinberg, the standard model describes everything from Newton's laws of motion to the behavior of subatomic particles with what is known as quantum mechanics. Most of what physicists know about the universe can be described by what is called the standard model of particle physics. Its simplicity makes it one of the best objects for experiments in nuclear physics.Ī property of the deuteron known as a magnetic quadrupole moment could reveal sources of a phenomenon known as time reversal violation, Van Kolck and his collaborators, including recently graduated UA doctoral student Emanuele Mereghetti, show in a recent paper published in Physical Review Letters.
The physics world was rocked recently by the news that a class of subatomic particles known as neutrinos may have broken the speed of light.Īdding to the rash of new ideas, University of Arizona theoretical physicist Bira van Kolck recently proposed that experiments with another small particle called a deuteron could lead to an explanation for one of the most daunting puzzles physicists face: the imbalance of matter and antimatter in the universe.Ī deuteron is a simple atomic nucleus, or the core of an atom.
