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…
Analytic decomposition of two-body electroweak processes with left-hand cuts
André Baião-Raposo, Raúl A. Briceño, Nicolas Lang +2
We derive an on-shell representation for electroweak transition amplitudes involving two hadrons in both the initial and final state for systems where there are left-hand…
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…
Timelike meson form-factors beyond the elastic region from lattice QCD
Felipe Ortega-Gama, Jozef Dudek, Robert Edwards
We present a calculation of the vector-isovector timelike form-factors of the pion and the kaon using lattice quantum chromodynamics. We calculate two-point correlation functions w…
Two-current transition amplitudes with two-body final states
Keegan H. Sherman, Felipe G. Ortega-Gama, Raúl A. Briceño +1
We derive the on-shell form of amplitudes containing two external currents with a single hadron in the initial state and two hadrons in the final state, denoted as $1+\mathcal{J}\t…
On-shell representations of two-body transition amplitudes: single external current
Raúl A. Briceño, Andrew W. Jackura, Felipe G. Ortega-Gama +1
This work explores scattering amplitudes that couple two-particle systems via a single external current insertion, . Such amplitudes can provide structural info…
