Plasmons, Gauge Invariance, and Mass

Schwinger has pointed out that the Yang-Mills vector boson implied by associating a generalized gauge transformation with a conservation law (of baryonic charge, for instance) does not necessarily have zero mass, if a certain criterion on the vacuum fluctuations of the generalized current is satisfied. %'e show that the theory of plasma oscillations is a simple nonrelativistic example exhibitin...

Gauge Invariance with Mass: Higher Spins in Cosmological Spaces

I review recent work on massive higher (s > 1) spins in constant curvature (deSitter) spaces. Some of the novel properties that emerge are: partial masslessness and new local gauge invariances, unitarily forbidden ranges of mass, correlation between fermions/bosons and nagative/positive cosmological constant Λ and finally the consistency requirement that in the limit of infinite spin towers, Λ ...

Effective QED actions: Representations, gauge invariance, anomalies, and mass expansions

We analyze and give explicit representations for the effective Abelian vector gauge field actions generated by charged fermions with particular attention to the thermal regime in odd dimensions, where spectral asymmetry can be present. We show, through z-function regularization, that both small and large gauge invariances are preserved at any temperature and for any number of fermions at the us...

Gauge invariance 1 Introduction

Up until now, we have dealt with general features of quantum field theories. For example, we have seen how to calculate scattering amplitudes starting from a general Lagrangian. Now we will begin to explore what the Lagrangian of the real world could possibly be. Then, of course, we will discuss what it actually is, or at least what we have figured out about it so far. A good way to start under...

Gauge Invariance and Noncommutativity *

The role of the gauge invariance in noncommutative field theory is discussed. A basic introduction to noncommutative geometry and noncommutative field theory is given. Background invariant formulation of Wilson lines is proposed. Duality symmetries relating various noncommutative gauge models are being discussed. ∗Work supported by RFBR grant #, INTAS grant # and Scientific School Support grant #.
