讲座摘要：I present the calculation of gravitational form factors of the nucleon in baryon chiral perturbation theory. I also briefly discuss the relation of these quantities to the internal structure of the hadrons.

主讲人简介：Jambul Gegelia is a researcher from Institute of Theoretical Physics, Ruhr Bochum University, Germany. In 2001, he got his PhD degree at Flinders University of South Australia, Adelaide, Australia. He took a posdoctoral position at INFN, Ferrara, Italy during 2001-2002. Since 2002, he held positions in Germany. He works on theoretical particle and nuclear physics. His research interest includes effective field theories, chiral perturbation theory, effective field theory approach to few-body problems, standard model coupled to gravity as an effective field theory. In particular, he and his collaborators proposed the so-called extended-on-mass-shell scheme, which has been extensively used in hadron physics.
