## Introduction to stringh theory

##### Course details

Quantization of the superstringSpectrum and partition functions. Vertex operators and scattering amplitudes. D-branes theory. Compactiffications and low energy actions. Dualities and holography.

##### Objectives

LEARNING OUTCOMES:

The course aims to introduce the basic elements of string theory and its applications to the study of theories of gauge and gravity. The expected learning outcomes include the understanding of the dynamics of open and closed strings at the classical and quantum level, and the study of the effective theories describing string interactions at low energy.

KNOWLEDGE AND UNDERSTANDING:

Students are expected to acquire a deep understanding of the dynamics of the quantum theories of open and closed strings, the spectrum of string states and the gauge and gravity effective theories describing the low energy physics of string theories. The knowledge and understanding will be measured through a oral and written exame.

APPLYING KNOWLEDGE AND UNDERSTANDING:

Students should be able to able to identify the D-brane realization of a particle physics or gravity model.
