ICTP-SAIFR/ExoHad School on Few-Body Physics: Nuclear Physics from QCD

October 16 – 25, 2024

ICTP-SAIFR, São Paulo, Brazil

IFT-UNESP Auditorium


Strongly interacting few-body systems are prevalent in many areas of nuclear and particle physics, from understanding the nuclear reactions responsible for the energy production in stars, to the observed emergent scaling behavior of three-body interactions. Tremendous progress has been made in establishing rigorous connections between nuclear few-body reactions to the fundamental degrees of freedom of Quantum Chromodynamics (QCD). Modern research in few-body phenomena requires a synergistic approach between various techniques from scattering theory, effective field theories, and lattice field theories to provide a global framework to compute non-perturbative observables from low-energy QCD.

The school will consist of four 4-hour courses on the topics of relativistic scattering theory, effective field theories (EFTs), lattice methods (both EFT and QCD), and finite-volume physics. Included in this course are practical exercise sessions to apply these tools to examples common for the study of few-body hadron and nuclear processes. Additionally, there will be a virtual three-day course before the school to prepare the participants on the fundamentals of non-relativistic scattering theory, particle and nuclear physics, and field theory.

Opportunity of paid internship at the University of California, Berkeley: At the end of the school, students will take an exam on the topics covered. Based on their exam scores, the top student(s) may be chosen to receive an all-expenses paid research internship from June-August 2025 at the University of California in Berkeley, California, USA. Paid expenses include lodging, travel, and visa fees. The student will be matched with a research mentor, who will guide them during their two-month internship. Furthermore, the student will be invited to participate in the next summer school and workshop hosted by the ExoHad collaboration, which is sponsored by the U.S. Department of Energy.

There is no registration fee and limited funds are available for travel and local expenses.

Additional Information

Attention! Some participants in ICTP-SAIFR activities have received email from fake travel agencies asking for credit card information. All communication with participants will be made by ICTP-SAIFR staff using an e-mail “@ictp-saifr.org”. We will not send any mailings about accommodation that require a credit card number or any sort of deposit.

BOARDING PASS: All participants, whose travel has been provided or will be reimbursed by ICTP-SAIFR, should bring the boarding pass  upon registration. The return boarding pass (PDF, if online check-in, scan or picture, if physical) should be sent to secretary@ictp-saifr.org by e-mail.

COVID-19: Brazilians and foreigners no longer have to present proof of vaccination before entering the country.

Visa information: Nationals from several countries in Latin America and Europe are exempt from tourist visa. Nationals from Australia, Canada and USA are exempt from tourist visa until April 10, 2025. Please check here which nationals need a tourist visa to enter Brazil.

Accommodation: Participants, whose accommodation will be provided by the institute, will stay at The Universe Flat. Hotel recommendations are available here.

How to reach the Institute: The school will be held at ICTP South American Institute, located at IFT-UNESP, which is across the street from a major bus and subway terminal (Terminal Barra Funda). The address which is closer to the entrance of the IFT-UNESP building is R. Jornalista Aloysio Biondi, 120 – Barra Funda, São Paulo. The easiest way to reach us is by subway or bus, please find instructions here.
