New experimental limits on the Pauli forbidden transitions in ${}^{12}$C nuclei obtained with 485 days Borexino data

The Borexino Collaboration

The Pauli exclusion principle (PEP) has been tested for nucleons ($n,p$) in ${}^{12}C$ with the Borexino detector.The approach consists of a search for $\gamma$, $n$, $p$ and ${\beta }^{\pm }$ emit…
