BaBar searches for new physics in invisible decays
Updated: 2013-01-30 00:00:00
On the hunt for physics beyond the Standard Model, scientists recently searched BaBar data for evidence of invisible particles.
Scientists analyzing data from the BaBar experiment, which operated at SLAC between 1999 and 2008, recently published the results of a search for signs of invisible particles: exotic bits of matter that interact so weakly with ordinary stuff they left no mark in the BaBar detector. In the process the researchers established much better limits on possible physics not contained within the Standard Model, which is currently the best explanation for the behavior of matter and the fundamental forces that shape it.
The pursuit of dark matter and dark energy s one of the most exciting—and most hallenging—areas of science. Now researchers hink they’e beginning to close in.
If you could use only 5 percent of the alphabet, you’d be stuck with the letter A. Five percent of a complete daily diet is a slice of dry toast.
Yet that’s all we have, or at least all we can perceive, of the place we call home.
Less than 5 percent of the universe is ordinary matter made of quarks, electrons and neutrinos.

It takes my eyes a few moments to adjust when I walk out the door of the Victor M. Blanco telescope in Chile around 2 a.m. I take a few careful steps into the moonless October night with a physicist and a software developer following close behind. We are working the overnight shift at the Cerro Tololo Inter-American Observatory, monitoring the newly installed Dark Energy Camera.

Scientific Goals and Pathways for Exploration of the Outer Solar System Solar System Exploration Roadmap Outer Planets Assessment Group The Outer Planets Assessment Group was established by NASA in late 2004 to identify scientific priorities and pathways for exploration in the outer solar system . The group consists of a 15-person steering committee which actively solicits input from the scientific community and reports its findings to NASA Headquarters . OPAG provides input to NASA but does not make . recommendations OPAG Charter OPAG is NASA's community-based forum designed to provide science input for planning and prioritizing outer planet exploration activities for the next several decades . It is chartered by NASA's Solar System Exploration Division and reports its findings at
