DESCRIPTION:Speakers: Vladimir Braun (University of Regensburg)\n\nAbstrac
 t:\nAlthough conformal symmetry is broken by quantum corrections in QCD\, 
 it can be exploited by embedding the four-dimensional theory in a suitably
  tuned non-integer spacetime dimension\, d=4−2ϵ\,where conformal symmet
 ry is restored at the Wilson–Fisher critical point. This observation has
  led to powerful new methods for tackling problems of considerable computa
 tional complexity. In this talk\, I will introduce the key ideas behind th
 is approach and discuss selected applications\, including renormalization 
 group equations for off-forward processes\, higher-twist corrections to de
 eply virtual Compton scattering (DVCS)\, heavy-quark physics\, and the fac
 torization of rapidity divergences.\nBiography:\nProf. Vladimir Braun is a
  theoretical physicist at the University of Regensburg\, Germany. His rese
 arch interests include quantum chromodynamics (QCD)\, hadron structure\, h
 ard exclusive processes\, and perturbative and nonperturbative aspects of 
 strong interactions. He has authored more than 180 papers\, which have rec
 eived over 25\,000 citations。He has made pioneering contributions to the
  theoretical understanding of hadron structure and QCD dynamics. He develo
 ped fundamental methods for the renormalization and evolution of gauge-inv
 ariant light-ray operators and uncovered a remarkable connection between Q
 CD evolution equations and integrable quantum spin chains. He has made sem
 inal contributions to the theory of hadron light-cone distribution amplitu
 des\, particularly their conformal expansion and higher-twist structure\, 
 as well as to the development of light-cone sum rules for hadronic form fa
 ctors. His work on renormalons has deepened our understanding of the inter
 play between perturbative and nonperturbative QCD. More recently\, he has 
 made important contributions to precision calculations for deeply virtual 
 Compton scattering and to the theoretical development of quasi- and pseudo
 -parton distributions relevant to lattice QCD.\nHost: Prof. Wei Wang\nAlte
