AB The internal structure of the lowest-lying pseudo-scalar mesons with heavy-light quark content isthoroughly studied using an algebraic model that has been successfully applied to similar physicalobservables of pseudoscalar and vector mesons with hidden-flavor quark content, ranging fromlight to heavy quark sectors. This model is based on constructing simple and evidence-basedansätze for the mesons’ Bethe-Salpeter amplitude (BSA) and quark propagator, allowing theBethe-Salpeter wave function (BSWF) to be computed algebraically. Its projection onto the lightfront yields the corresponding light-front wave function (LFWF), which provides easy accessto the valence-quark Parton Distribution Amplitude (PDA) by integrating over the transversemomentum squared. We leverage our current knowledge of the PDAs of the lowest-lying pseudoscalar heavy-light mesons to compute their Generalized Parton Distributions (GPDs) via theoverlap representation of the LFWFs. From this three-dimensional information, various limits andprojections allow us to deduce the related Parton Distribution Functions (PDFs), ElectromagneticForm Factors (EFFs), and Impact Parameter Space GPDs (IPS-GPDs). Whenever possible, wemake explicit comparisons with available experimental results and previous theoretical predictions
