Dear everyone, please join us for Ronen's seminar on Tuesday afternoon,
3:30 PM PST.  Zoom coordinates are here:
https://urldefense.proofpoint.com/v2/url?u=https-3A__hit.lbl.gov&d=DwIFaQ&c=CJqEzB1piLOyyvZjb8YUQw&r=cENV01DigFZ7zdrPdEH56A&m=qMiUFxdPjpK4RrTs8VBFgmXiA83sYBiRvYun_0w_uFhrgYL4AIWpi9jzsNLUtLVm&s=fIKWQqz_2BqxgFVYPQOPrpCAsKwHcLPoaPuMsBdK22M&e= 
I will be hosting local folks in the theory lounge, please join us there if
you can.  We will have tea and cookies there, and the espresso machine too.

The physics is interesting and timely, Ronen's abstract is pasted in at the
end.
All the best,

Short-range expansion and three-nucleon correlations in nuclear systems

An accurate description of short-range physics is one of the main
challenges in the study of strongly interacting many-body quantum systems.
In nuclear systems, short-range correlations (SRCs) have been studied
extensively in the last decades using both large momentum transfer
quasi-elastic reactions and ab-initio calculations. In this talk, I will
present an overview of the Generalized Contact Formalism, an effective
model based on the short-range factorization of the many-body wave
function, that allows to obtain a comprehensive picture of the effects of
SRCs in nuclei. I will then discuss recent results in which first signature
of three-nucleon correlations is observed. I will also present an extension
of the formalism which includes sub-leading corrections to the
wave-function factorization, towards a systematic short-range expansion of
the nuclear many-body problem. Finally, I will show an application for the
calculation of neutrinoless double beta decay matrix elements.
