Boss quasars track expanding universe The most precise measurement yet
2014/4/16
The Baryon Oscillation Spectroscopic Survey (BOSS), the largest component of the third Sloan Digital Sky Survey (SDSS-III), pioneered the use of quasars to map density variations in intergalactic gas ...
Precise measurement of the e+e－→π+π－(γ) cross section with the initial state radiation method at BABAR
pion form factor ISR g-2 BABAR
2010/5/7
We present a precise BABAR measurement on the cross section of the process e+e－→π+π－(γ) from threshold to an energy of 3 GeV with the initial state radiation (ISR) technique, using 232 fb－1 of data co...
