У оквиру платформе за теоретичаре високих енергија са Балкана, Balkan String Webinar, у петак, 5. децембра 2025. године у 14 CET, онлајн предавање под насловом ”The thermal representation of conformal ladder integrals” одржаће Анастасиос Петкоу са Универзитета Арисотел из Солуна, Грчка.
САЖЕТАК:
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.
