Measurements at the LNF BTF
Main goal Evaluate the smearing in the position resolution produced by
multiple scatterings of beam e- in the telescope planes (@ BTF).
(Exp. Residual)² = (Intr. Resolution)² + (Mult. Scatt. Residual)²
Procedure
1.Reproduce the telescope geometry in GEANT (no pixelization introduced)
2.Simulate the beam (electrons)
3.Follow the propagation and the interactions of the beam particles with the materials
4.Save GEANT hit position in each plane
5.Reconstruct the tracks by processing the data with TAF
6.The result is then subtracted to the overall experimental resolution

- analyses of the 2002-2005 KLOE data -> publications
- Step 0 : Pure Carbon Target inside KLOE data taking in 2012, under analyses
-> publ.
- R&D for more refined setup: trigger and active target
- in 2014: collaboration AMADEUS+KLOE for KLOE2 data taking and
studies of future possible scenario and addings (hypernuclear…)
- AMADEUS dedicated setup: formation of a strong collaboration; technical
proposal – ongoing (EU projects….) – interest from: Vienna; Heidelberg;
TUM; GSI; Varsavia; IFIN-HH; Moscow ITEP; Cracovia; Zagreb; RIKEN ….

12 researchers for 6.5 FTE
Average participation of 54%
Total INFN 5.8 FTE
VIP=Violation Pauli Exclusion Principle (PEP)
Perform experimental test of PEP for e- with a clean method
Located at LNGS to reduce X-ray background
International collaboration: LNF, LNGS, Ts INFN; SMI-OAW (Austria); IFIN-HH
(Romania); Neuchatel U. (Switzerland)
VIP already established a probability of PEP violation b2/2<4x10-29
previous limit <1.7x10-26 PLB 328 (1990) 438
VIP upgrade (CCD detectors replaced by SDD) – goal to gain a factor 100
Other tests of Quantum Mechanics (collapse models)
ALL Responsabilities @ LNF
Previous limit improved by 3 orders of magnitude
International Journal of Quantum Information 9 (2011) 145
“Quantum explorations: from the waltz of the Pauli
exclusion principle to the rock of the spontaneous
collapse” (Phys. Scr. 90 (2015) 028003): paper of the week

VIP2= Upgraded VIP setup –
tests and measurements at SMI-Vienna
VIP
VIP2 tested @ LNF (2014) and moved to SMI for tests and measurements
Alessandra Fantoni – CL preventivi 2016
Upgraded VIP setup
VIP
- Detector ready to be moved from Vienna to LNGS (problems with the
impossibility to use sources for calibration, new rules....)
- Within 2015: start data taking with upgraded setup (but still old SDDs)
- Expectation either to find a small violation or to be able to bound the
probability that PEP is violated by electrons pushing it from about 4·10-29
to 10-31
- Expected period of data taking: 3-4 years
Explore other type of other type quantum mechanics tests
(collapse model predictions)
