Comparisons of annual modulations in MINOS with the event rate
modulation in CoGeNT

Αγγλικά

The CoGeNT Collaboration has recently published results from a fifteen
month data set which indicate an annual modulation in the event rate
similar to what is expected from weakly interacting massive particle
interactions. It has been suggested that the CoGeNT modulation may
actually be caused by other annually modulating phenomena, specifically
the flux of atmospheric muons underground or the radon level in the
laboratory. We have compared the phase of the CoGeNT data modulation to
that of the concurrent atmospheric muon and radon data collected by the
MINOS experiment which occupies an adjacent experimental hall in the
Soudan Underground Laboratory. The results presented are obtained by
performing a shape-free chi(2) data-to-data comparison and from a
simultaneous fit of the MINOS and CoGeNT data to phase-shifted
sinusoidal functions. Both tests indicate that the phase of the CoGeNT
modulation is inconsistent with the phases of the MINOS muon and radon
modulations at the 3.0 sigma level. DOI: 10.1103/PhysRevD.87.032005
