---++ !PiENu

The PIENU experiment aims at precisely measuring the pion decay branching ratio (&#960;+ &#8594; e&#957;)/(&#960; &#8594;&#956;&#957;).  
The current experimental value for this ratio is 20 times less precise than the theoretical calculation done within the SM, leaving a large window in which non-standard physics - new interactions or exotic particles - can be involved. Or, on the other hand, improved precision that would confirm the SM would set tighter constraints on new physics scenarios.

---+++ Code compilation

The MC code was obtained from =svn=  (pienu02.triumf.ca/pienumc/trunk) and unpacked on the UI. Specific versions of CLHEP (2.0.4.2) and Geant4 (4.9.0.3.p02) were installed in the user directory in =~/packages/=.
Detailed download and compilation instructions for CLHEP, Geant4 and the main pienu code were provided by Aleksey Sher via email (May 2011).
