3. The MINERvA Collaboration
At present-day, the
MINERvA Collaboration
is constituted by ca. 120
nuclear and particle
physicists from 22
institutions in 7
countries.

4. The MINERvA Detector
GOALS:
• Multiple ν-A interaction cross sections (broad
range of A)
• Exclusive final state and differential cross
sections
• Exclusive final states and inclusive scattering.
• Form factors and structure functions
• Nuclear effects on the ν-A interactions

5. MINERvA´s Timeline
SUMMARY:
November 2009:
- MINERvA starts taking data with 55% of the detector and
some nuclear targets.
January - March 2010:
- Install remaining detector
- Start taking neutrino data
November 2010:
- Start antineutrino data

6. MINERvA´s Timeline (cont.)
2010 and beyond:
Data acquisition for:
LE configuration (3 GeV)
ME configuration (8 GeV)
ν and anti-ν
All targets (H2O, He, C, Fe, Pb)
Special runs to understand the flux
Cross-section experiments
MC Simulations for experimental data
Data processing, validation, etc.

8. a compact, fully
active neutrino
detector that uses
the NuMI beam line
to study neutrino-
nucleus interactions
with unprecedented
detail.
The detector is
directly located
upstream of the
MINOS Near
Detector.

22. Summary
MINERvA has unique ability to answer numerous
puzzles seen in current cross section data
MINERvA can effectively select CCQE events
Work ongoing on an increased data set with the
goal of producing CCQE cross section results . . .
pronto !
Expectation: New Understanding of Neutrino
Interactions . . . just around
the corner !
