**Big Bang Nucleosynthesis and Physics Beyond the Standard Model**

by Subir Sarkar

**Publisher**: arXiv 1996**Number of pages**: 156

**Description**:

We first present a pedagogical account of relativistic cosmology and primordial nucleosynthesis, discussing both theoretical and observational aspects, and then proceed to examine such constraints in detail, in particular those pertaining to new massless particles and massive unstable particles. Finally, in a section aimed at particle physicists, we illustrate applications of such constraints to models of new physics.

**Jerome Martin**-

**arXiv**

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.
