The two-body scattering lengths in nuclear physics are (much) larger than the typical interaction length which is given by the inverse of the pion mass; this natural fine-tuning places nuclear physics inside the universality window of Efimov physics. 

In this talk, I'll give a brief introduction to Efimov physics and I'll show to which extent it is a good spot to observe and to understand the nature of the spectrum of light nuclei.
