New results from AMS presented at ICRC 2013

July 8th, 2013

Using the data collected during more than 2 years the AMS Collaboration presented at ICRC 2013 new physics results on

1) Proton spectrum from 1 GV to 1.8 TV and searches for spectral breaks

2) Helium spectrum from 2 GV to 3 TV and searches for spectral breaks

3) Electron spectrum from 1 GeV to 500 GeV

4) Positron spectrum from 1 GeV to 350 GeV

5) Positron+Electron spectrum from 0.5 Gev to  700 GeV

6) B/C ratio from 0.5 GV to 500 GV

7) Positron fraction and Positron fraction anisotropy (update with respect to the PRL paper)

Most of these results are based on statistical and  systematic errors at O(1%).

Alltogether the AMS Collaboration has presented to ICRC 2103: 1 highlight talk by S. C. C. Ting, 7 physics talk on a parallel section devoted to AMS and 17 papers about the operation of the experiment on board of the ISS
