Dear All, 

Here is a for the cake seminar tomorrow:
> 
> Wednesday, March 6th, 1:00PM, Room L102


> Pawel Sznajder (National Centre for Nuclear Research, Warsaw), "Towards extraction of GPDs: Unbiased determination of DVCS Compton Form Factors"
> 
> Abstract:
> I will present analysis of nearly all existing Deeply Virtual Compton Scattering (DVCS) data allowing to explore the proton structure within the framework of Generalised Parton Distributions (GPDs).  This analysis starts from a model-independent determination of DVCS amplitudes using the neural network technique. This approach is complementary to our last global analysis of DVCS data, where parameterisations of DVCS amplitudes are constructed in a model-dependent way to fulfil the basic properties of GPDs. Comparison of both analyses allows to estimate the model dependency of quantities extracted and interpreted in the framework of GPDs. The work is done within the PARTONS framework being the modern tool for generic GPD studies.
