Thanks everyone for a great workshop, see you again soon!

We are thrilled to invite you to NuXTract, a new in-person NuSTEC workshop scheduled for the week of October 2nd 2023 at CERN from Monday 2nd 2pm until Friday 6th 1pm. 

This special workshop will be dedicated to open issues in neutrino cross-section extraction, and data presentation and preservation efforts. It is an excellent opportunity for experiments to discuss how they present data, for theorists to specify their needs from a data release, and for all of us to dive into the statistical challenges in cross-section extraction (e.g. unfolding, regularisation methods, efficiency corrections, background constraints). 

The agenda will be composed of invited talks, selected abstracts, and lots of discussions. 

A google doc is available in this link to all participants to share their thoughts, questions, discussion points 

We have high hopes and wish to come out of this workshop with a set of NuSTEC best-practice guidelines for how to extract a cross-section measurement, and start a neutrino cross-section database with comparable results we know how to interpret.

The workshop will bring together both experts and early career scientists to share experiences with cross-section extraction challenges and use of experimental data releases. We will also hear about data preservation efforts and novel approaches to cross-section extractions (e.g. forward folding or ML methods). 

If you wish to take part, please mark your schedules, be sure to register and to submit an abstract using the links on the left of this page if you wish to attend and/or present anything.

We hope to see many of you there!


We are planning on hosting a social buffet on Thursday evening as well as providing coffee and snacks. To cover this, we will ask for a small attendance fee of 100 CHF for those attending in person. Please pay the using this form. 


CERN has a hotel on site close to our workshop rooms. We have booked 50 of these rooms for the workshop that will be available until 30 days before the workshop. If you want to book one of these, please use this booking form. Leave the team account / budget code part empty. If you have any trouble accessing the form or booking a room please contact the organisers.

Abstract submission and registration deadline: August 31st.
