[hep-th] Balkan String Webinar – 5 December – Tassos Petkou

[Mihailo Čubrović]

Dear colleagues,

Next Friday, 5th December,
at 14:00 CET,
Tassos Petkou (Aristotle U. Thessaloniki, Greece) will give an online 
talk.

Title: The thermal representation of conformal ladder integrals

Abstract: I will present details of a recently discovered representation 
of conformal four-point ladder integrals as thermal one-point functions 
in scalar field theories. Conformal ladder integrals can be constructed 
from the partition function of two harmonic oscillators twisted by an 
imaginary chemical potential. For any even dimension D and any loop 
order L they satisfy a familiar-looking second order differential 
equation. Thermal one-point functions of higher-spin operators 
correspond to linear combinations of multi-loop ladder graphs in D= 2 
and D= 4 dimensions. A simple derivation for the all-loop resummation of 
conformal ladder integrals for arbitrary D is also given. Some possible 
connections of this work and recent developments in the thermal 
bootstrap, multiloop calculations, integrability, AdS/CFT and string 
theory will be discussed.
