An early-career physicist mathematically connects timelike and spacelike form factors, opening the door to further insights into the inner workings of the strong force. A new lattice QCD calculation connects two seemingly disparate reactions involving the pion, the lightest particle governed by the strong interaction. One reaction is known as the spacelike process, where an electron is bounced off a pion. The second reaction, known as the timelike process, is when an electron and antielectron collide, annihilate each other, and produce two pions. The lattice QCD numerical calculation is simultaneously able to describe the spacelike and timelike processes, demonstrating the interconnectedness of different reactions described by QCD. While this connection had been observed experimentally, now physicists have the math to corroborate it.

The new adaptive optical devices are designed to deliver ring-like targeted heating patterns to the surface of the 34-cm-diameter core optics in LIGO to control the effect of increasing thermal distortion as the laser power is increased toward the megawatt scale.

Stony Brook University physicists Gabor David and Axel Drees sketch out how a signal of jet energy loss in deuteron-gold collisions at the Relativistic Heavy Ion Collider (RHIC) supports the case that these collisions create small specks of quark-gluon plasma, a form of matter that permeated the early universe.

The image shows the predicted flux of antihelium-3 produced from dark matter (WIMPs) that annihilate producing these antinuclei. Each color represents the prediction for a different mass of dark matter, as shown in the legend. t The bands are almost touching the AMS-02 sensitivity, which means that in some optimistic cases, WIMPs can explain this discrepancy.
