Physics experiment explores antimatter asymmetry
DOE/Los Alamos National Laboratory
A new paper out in Nature describes unusual results from the E-906/SeaQuest experiment, showing that distributions of antiquarks are significantly different than expected, with more abundant down type antimatter quarks than up antimatter quarks.
LOS ALAMOS, N.M., February 24, 2021 A complex high-energy nuclear physics experiment, aiming to measure the contributions of antiquarks to the structure of the proton and neutron, has produced results that are the opposite of what had previously been understood about proton structure and the dynamics of strong interacting antiquarks and gluons. The main physics result of this experiment has very significant impact on our understanding of the proton structure, and also on the dynamics of strong interacting antiquarks and gluons inside the proton, said Ming Xiong Liu, a Los Alamos National Laboratory author on the new paper, which was published in the

The Dark Energy Survey has released a massive, public collection of astronomical data and calibrated images from six years of work. Containing data on nearly 700 million astronomical objects, this second data release in the Survey s seven-year history is the topic of sessions today and tomorrow at the 237th Meeting of the American Astronomical Society.[1]
