The study of Standard Model (SM) physics is very important at the LHC.
Before any discovery can be claimed a detailed understanding
of the detectors should be reached and benchmark SM processes should be
measured. A precise measurement of the various parameters is crucial as a
consistecy check of the SM. Moreover, SM processes can be directly sensitive
to new physics, they will allow to...

Borexino is a low threshold liquid-scintillator detector for solar neutrinos located in the LNGS underground laboratory, Italy. Because of the ultra-high radio purity it is the first experiment able to do a real time analysis of the low energetic solar neutrinos.
A detection of the solar ⁷Be neutrinos with a rate of 47+-7 counts/day/100tons was reported (192 days of live time measurement). ⁸B...
