Physics Beyond the Standard Model and Dark Matter

Authors: Hitoshi Murayama
(Submitted on 18 Apr 2007)

Abstract: In this lecture note, I discuss why many of us are expecting rich physics at the TeV scale, drawing analogies from the history of physics in the last century. Then I review some of the possible candidates of new physics at this energy scale. I also discuss why we believe much of the matter in the universe is not atoms (baryons) or compact astronomical objects, and hence requires physics beyond the standard model. Finally I discuss some of the candidates for the non-baryonic dark matter.

Spontaneous Symmetry Breaking as a Basis of Particle Mass

Authors: Chris Quigg
(Submitted on 17 Apr 2007 (v1), last revised 28 May 2007 (this version, v2))

Abstract: Electroweak theory joins electromagnetism with the weak force in a single quantum field theory, ascribing the two fundamental interactions--so different in their manifestations--to a common symmetry principle. How the electroweak gauge symmetry is hidden is one of the most urgent and challenging questions facing particle physics. The provisional answer incorporated in the "standard model" of particle physics was formulated in the 1960s by Higgs, by Brout & Englert, and by Guralnik, Hagen & Kibble: The agent of electroweak symmetry breaking is an elementary scalar field whose self-interactions select a vacuum state in which the full electroweak symmetry is hidden, leaving a residual phase symmetry of electromagnetism. By analogy with the Meissner effect of the superconducting phase transition, the Higgs mechanism, as it is commonly known, confers masses on the weak force carriers W and Z. It also opens the door to masses for the quarks and leptons, and shapes the world around us. It is a good story--though an incomplete story--and we do not know how much of the story is true. Experiments that explore the Fermi scale (the energy regime around 1 TeV) during the next decade will put the electroweak theory to decisive test, and may uncover new elements needed to construct a more satisfying completion of the electroweak theory. The aim of this article is to set the stage by reporting what we know and what we need to know, and to set some "Big Questions" that will guide our explorations.

Lectures on QED and QCD

Authors: Andrey Grozin
Comments: LaTeX2e, 103 pages, 62 figures. The complete paper is also available at this http URL

The lectures are a practical introduction to perturbative calculations in QED and QCD. I discuss methods of calculation of one- and two-loop diagrams in dimensional regularization, MSbar and on-shell renormalization schemes, decoupling of heavy-particle loops.
