Everything You Always Wanted To Know About The Cosmological Constant Problem
by Jerome Martin - arXiv , 2012
This text discusses the cosmological constant problem at a pedagogical but fully technical level. We review how the vacuum energy can be regularized in flat and curved space-time and how it can be understood in terms of Feynman bubble diagrams.
