Resolving the with Exchange from Lattice QCD
Nelson Pitanga Lachini, Raúl A. Briceño
We revisit the lattice QCD description of the doubly charmed tetraquark using a finite-volume scattering formalism that incorporates one-pion exchange nonperturbatively,…
Two bodies left behind
Raúl A. Briceño, Caroline S. R. Costa, Hans-Werner Hammer +1
We consider scenarios in which a shallow bound state undergoes breakup by a probe whose energy is high compared to the binding energy. The first two scenarios, which serve as warm-…
Resolving the structure of bound states using lattice quantum field theories
Joseph Moscoso, Felipe G. Ortega-Gama, Raúl A. Briceño +3
This work presents the first lattice calculation of a two-to-two particle matrix element of a local current. This exploratory calculation is performed using a leading-order pionles…
Introduction to Lattice Field Theory
Raúl A. Briceño
This chapter provides a pedagogical introduction to lattice quantum field theory, with strong emphasis on lattice quantum chromodynamics. The chapter reviews key foundational conce…
