[Theory-seminars] Seminars next week

[Christopher Thomas]

Dear all,

As well as the theory seminar on Monday (March 15, 1pm, L104), we have a
cake seminar on Wednesday (March 17, 3pm, L104).  Details below:


-----
Monday, March 15th
1pm (coffee at 12:45pm)
Room L104

*Coupled channel effects in meson photo and electroproduction at high 
energy*
	
Jean-Marc Laget
JLab

In the energy range accessible at JLab6 and JLab12, the coupling to the
vector meson production channels provides us with a natural explanation 
of two long standing problems: i) the magnitude of the cross section of 
charged pion photoproduction near 90 degrees and its scaling behavior 
(s^-7), ii) the strong cross section of the neutral pion 
electroproduction at large Q^2 recently measured at JLab. I will present 
this approach which relates the amplitudes of several reactions recently 
determined at JLab.

*Exotic and excited-state radiative transitions in charmonium from 
lattice QCD*

Christopher Thomas
JLab

I will discuss recent calculations of meson radiative transition form 
factors in lattice QCD.  Results in the charmonium region, involving 
excited charmonium states, states of high spin and exotics, will be 
presented and I will highlight interesting results involving an exotic 
1-+ and a vector-hybrid candidate.  I concentrate on the phenomenology 
of the results, comparing with experimental data and with models.  To 
conclude I give comments on future prospects, including application to 
light mesons.
