SUMMARY:Ben Hoare Durham - 
DESCRIPTION:Prof. Ben Hoare (Durham)\n\nTitle: Yang-Baxter deformations of 
 the Principal Chiral Model plus Wess-Zumino term\n\nAbstract:\nIn this tal
 k we will discuss integrable deformations of the Principal Chiral Model (P
 CM) plus Wess-Zumino (WZ) term. Adding a WZ term to the PCM preserves inte
 grability\, as do the Yang-Baxter deformations. Both also preserve 1-loop 
 renormalisability\, but modify the RG flow in different ways. After derivi
 ng a cohomological condition that should be satisfied for both to be done 
 simultaneously\, we will give the expression for the deformed action and d
 iscuss its integrability. We will also briefly explore how this constructi
 on fits into various organisational frameworks such as E-models\, 4-d Cher
 n-Simons and non-abelian T-duality.
