Talk:Four-fermion interactions

This entire article is crap. These are not four-fermion interactions. They are quartic in the fermion operators but they represent only two-body interactions. The diagrams they correspond to have only two fermions at any given time. If you draw a time-ordered diagram, a horizontal line will only cross two fermion lines in the bare interaction.

Renormalized Hamiltonians create effective interactions which are potentially N-body, but this is not what this article is talking about. Whoever made up this article is an idiot. —Preceding unsigned comment added by Jeff60637 (talk • contribs) 24 May 2006

These kinds of interactions are generally called four-fermion interactions.
Name-calling is not only unconstructive, it also reflects poorly on the name-caller.

"In modern English usage, the terms "idiot" and "idiocy" describe an extreme folly or stupidity..." [Wikipedia: idiot]. Since it is my claim that this article represents extreme folly and stupidity, my comments were not name calling but rather a reasonable use of the modern English language. These interactions may generally be called four-fermion interactions but that does not make it a correct term. The truth is that there are no bare four fermion interactions anywhere in currently known physics and this article contains bad information and perpetuates ignorance. —Preceding unsigned comment added by Jeff60637 (talk • contribs) 23 April 2006
