Universality in strongly interacting bosonic clusters
L. Madeira, F. Pederiva, U. van Kolck
We develop an effective field theory (EFT) for strongly interacting bosonic clusters, using He as a paradigmatic example of universality in systems with large scattering length…
Three- and four-boson systems expanded around the unitarity limit: Application to He
Feng Wu, Xincheng Lin, Ubirajara van Kolck +1
The three- and four-boson systems with a large scattering length and a short effective range in the two-body sector are studied in the framework of Short-Range Effective Field Theo…
Two-Pion Exchange Contributions to the Nucleon-Nucleon Interaction from the Roper Resonance
Yang Xiao, Li-Sheng Geng, U. van Kolck
We derive the long-range components of the nucleon-nucleon (NN) two-pion-exchange potential with an intermediate Roper resonance. Leading-order interactions in heavy-baryon chiral…
The Three-Body Limit Cycle: Universal Form for General Regulators
Langxuan Chen, Feng Wu, Xincheng Lin +3
The Efimov effect, a remarkable realization of discrete scale invariance, emerges in the three-body problem with short-range interactions and is understood as a renormalization gro…
Baryon Number Violation: From Nuclear Matrix Elements to BSM Physics
Leah J. Broussard, Andreas Crivellin, Martin Hoferichter +19
Processes that violate baryon number, most notably proton decay and transitions, are promising probes of physics beyond the Standard Model (BSM) needed to understand the…
Nuclear Physics and the European Particle Physics Strategy Update 2026
L. M. Fraile, J. J. Gaardhøje, U. van Kolck +6
This document provides input to the update of the European Strategy for Particle Physics in fields that are related to Nuclear Physics as described in the NuPECC Long Range Plan 20…
