In Brief

COO meeting today at 9:30 a.m. in Ramsey Auditorium

An all-Office-of-the-COO meeting will be held today from 9:30-10:30 a.m. in Ramsey Auditorium.

If you work in one of the following departments, please plan to attend: WDRS, Office of Campus Strategy and Readiness, FESS, Office of Communication, Office of Integrated Planning and Performance Management, Legal Office, Office of Partnerships and Technology Transfer, and Illinois Accelerator Research Center.

From Dark Energy Detectives

Across the world and up all night

For the last week, detectives from the Dark Energy Survey have been coordinating across four continents to bring to light more evidence of how the fabric of space-time is stretching and evolving.

In Sussex, England, more than 100 detectives met to discuss the current state and the future of the survey that is conducted at the Blanco telescope, located at Cerro Tololo in Chile. At this semiannual collaboration meeting (with a new venue each time), we continued to strategize analyses for the many probes of space-time evolution and dark energy: As I write, several early results are being prepared for publication.

Wrinkles in space-time: the warped physics of the interstellar

From Wired, Oct. 22, 2014

Kip Thorne looks into the black hole he helped create and thinks, "Why, of course. That's what it would do." This particular black hole is a simulation of unprecedented accuracy. It appears to spin at nearly the speed of light, dragging bits of the universe along with it. (That's gravity for you; relativity is superweird.) In theory it was once a star, but instead of fading or exploding, it collapsed like a failed soufflé into a tiny point of inescapable singularity. A glowing ring orbiting the spheroidal maelstrom seems to curve over the top and below the bottom simultaneously.

Frontier Science Result: CDF

A charming result

These plots show the effective lifetime asymmetries as function of decay time for D →K+K- (top) and D → π+π- (bottom) samples. Results of the fits not allowing for (dotted red line) and allowing for (solid blue line) CP violation are overlaid.

Physicists gave funny names to the heavy quark cousins of those that make up ordinary matter: charm, strange, bottom, top. The Standard Model predicts that the laws governing the decays of strange, charm and bottom quarks differ if particles are replaced with antiparticles and observed in a mirror. This difference, CP violation in particle physics lingo, has been established for strange and bottom quarks. But for charm quarks the differences are so tiny that no one has observed them so far. Observing differences larger than predictions could provide much sought-after indications of new phenomena.

A team of CDF scientists searched for these tiny differences by analyzing millions of decays of particles decaying into pairs of charged kaons and pions, sifting through roughly a thousand trillion proton-antiproton collisions from the full CDF Run II data set. They studied CP violation by looking at whether the difference between the numbers of charm and anticharm decays occurring in each chunk of decay time varies with decay time itself.

The results have a tiny uncertainty (two parts per thousand) but do not show any evidence for CP violation, as shown in the upper figure. The small residual decay asymmetry, which is constant in decay time, is due to the asymmetric layout of the detector. The combined result of charm decays into a pair of kaons and a pair of pions is the CP asymmetry parameter AΓ , which is equal to -0.12 ± 0.12 percent. The results are consistent with the current best determinations. Combined with them, they will improve the exclusion constraints on the presence of new phenomena in nature.
