Detailed Description

The module implements GPDs which appear in Goloskokov-Kroll (GK) model in pseudoscalar meson production.

This model is defined in the series of references:

arxiv:0906.0460 [10] ;
arxiv:1106.4897 [11] ;

Available GPD types: H, E, \tilde{H}, \tilde{E}, H_T and \bar{E}_T

We use the following parameters for GPDs (all GPDs have Regge-like profile function): 1) \tilde{H}: Table 1 in arxiv:1901.11380 with \alpha(0) = 0.32 2) \tilde{E}: Table 1 in arxiv:1901.11380 3) H_T: Table 1 in arxiv:1901.11380 with \alpha(0) = -0.17 4) \bar{E}_T: Table 1 in arxiv:1901.11380 with PDFs (forward-limits) parametrizations ABM: arXiv:1202.2281 and DSSV: arXiv:0904.3821
