We derive the effective low-energy theory for single-wall
carbon nanotubes including the Coulomb interactions among electrons.
The generic model found here consists of two spin-
fermion chains which are coupled by the interaction.
We analyze the theory using bosonization, renormalization-group
techniques, and Majorana refermionization. Several experimentally
relevant consequences of the breakdown of Fermi liquid
theory observed here are discussed in detail,
e.g., magnetic instabilities, anomalous conductance
laws, and impurity screening profiles.
