Pseudoscalar and vector toponia in a Dyson--Schwinger--Bethe--Salpeter framework
H. -R. Zhang, Z. -F. Cui, J. Segovia
We study the pseudoscalar () and vector () top--antitop (toponium) systems within the rainbow--ladder truncation of the Dyson--Schwinger and Bethe--Salpeter…

A Continuum Schwinger Method to Study the Pion's Generalized Parton Distribution
J. M. Morgado-Chávez, J. Segovia, F. de Soto +5
Generalised Parton Distributions (GPDs) provide multidimensional insight into hadron structure and are particularly relevant for the pion, whose dynamics are intimately linked to c…
