Novel approach to assess the impact of the Fano factor on the sensitivity of low-mass dark matter experiments Open
As first suggested by U. Fano in the 1940s, the statistical fluctuation of the number of pairs produced in an ionizing interaction is known to be sub-Poissonian. The dispersion is reduced by the so-called "Fano factor", which empirically e…
