First Two-Hadron Form Factor from QCD
Felipe G. Ortega-Gama, Raúl A. Briceño, Ivan M. Burbano +1
We present the first QCD determination of an energy-dependent form factor for a two-hadron scattering state. In particular, we calculate the QCD contribution to the forward electro…
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…
