String theory and its applications

1 Sept 2014, 08:00 → 26 Sept 2014, 18:00 Europe/Berlin

The program builds on two closely intertwined pillars: string phenomenology and gauge-string duality (‘gauge/gravity duality’). Topics in string phenomenology and string cosmology include the status of supersymmetry, the emergence of extra dimensions and the Higgs mechanism in string compactifications as well as implications of the preliminary LHC results on new gauge bosons and light string excitations. Further topics include stringy candidates for the dark sector, inflation, quark and lepton flavor structures in string theory; in the context of gauge/gravity duality, gauge mediation of supersymmetry breaking, the computation of scattering amplitudes using gauge-string dualities and newly developed perturbative methods using heavy forefront mathematics in theories with various amounts of supersymmetry and numerous advances in different aspects of field theories at strong coupling. Moreover, gauge/gravity duality relates black holes on the one hand with strongly coupled systems on the other. These systems include gauge theories at strong coupling with applications to the QCD phase diagram, as well as critical phenomena in condensed matter physics such as superconductivity. Both directions, string phenomenology and gauge/gravity duality, build on the same computational and mathematical methods, making an interchange between the two communities particularly fruitful.
Application deadline: 28 February 2014 (Later applications are possible until all places are filled)

The last week 22-26 September 2014 hosts the annual conference of the COST Action "The String Theory Universe", see https://indico.mitp.uni-mainz.de/conferenceDisplay.py?confId=15  for details.

Abstract: We establish a method to compute the Nekrasov partition functions of theories which arises from (p, q) 5-brane webs or M-theory compactifications on their dual Calabi-Yau threefolds.The theories include certain non-Lagrangian theories such as the T_N theory. For that, it is important to remove the contributions which are decoupled from the theory. The web diagram encodes the decoupled contributions in a simple way.We also develop a prescription to compute the instanton partition functions of theories which are obtained by the Higgsing the T_N theory. The theories include the Sp(1) gauge theories with 6 or 7 flavors which have E7 or E8 flavor symmetry respectively at their fixed points.
