[Theory-seminars] Seminars next week

[Carlota Andres Casas]

Dear all,

Here is a reminder for next week theory seminars:

Theory seminar:
Monday, March 4th, 1:00PM, Room L102
Srimoyee Sen (U. of Washington), "Anyonic particle-vortex statistics and the nature of dense QCD"

Abstract:
Recent theoretical observations have established the presence of Z_3 -valued
particle-vortex braiding phases in high density quark matter. Certain mesonic and baryonic excitations, in the presence of a superfluid vortex, have orbital angular momentum quantized in units of 1/3. Such non-local topological features can distinguish phases whose realizations of global symmetries, as probed by local order parameters, are identical. If Z_3 braiding phases and angular momentum fractionalization are absent in lower density hadronic matter, as is widely expected, then the quark matter and hadronic matter regimes of dense QCD
must be separated by at least one phase transition.


Theory seminar:
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.
