A simple solution to the strongCP-problem

- Physics
- 1983

We suggest soft breaking of Peccei-Quinn symmetry as a simple solution to the strongCP problem without the presence of the axion. In the context of theSU(2)L×U(1) model, it is shown how…

Small \bar{\theta } and an Invisible Axion as Automatic Consequences of Grand Unification

- Physics
- 1983

I explore the possibility of solving the strong CP problem in a grand unified theory in which a global Peccei-Quinn symmetry is an automatic consequence of the gauge structure. The low energy…

Strong CP problem, axions, and cosmological implications of CP violation

- Physics
- 2016

In this talk, I present a pedagogical and historical review related to the CP symmetry. It includes the weak CP violation, the strong CP problem, “invisible” axions and cosmology, and Type-II…

CP Conservation in the Presence of Pseudoparticles

- Physics
- 1977

We give an explanation of the $\mathrm{CP}$ conservation of strong interactions which includes the effects of pseudoparticles. We find it is a natural result for any theory where at least one flavor…

Problem of Strong $P$ and $T$ Invariance in the Presence of Instantons

- Physics
- 1978

The requirement that P and T be approximately conserved in the color gauge theory of strong interactions without arbitrary adjustment of parameters is analyzed. Several possibilities are identified,…

A new light boson

- Physics
- 1978

It is pointed out that a global U(1) symmetry, that has been introduced in order to preserve the parity and time-reversal invariance of strong interactions despite the effects of instantons, would…

Symmetry Breaking Through Bell-Jackiw Anomalies

- Physics
- 1976

In models of fermions coupled to gauge fields certain current-conservation laws are violated by Bell-Jackiw anomalies. In perturbation theory the total charge corresponding to such currents seems to…

Vacuum Periodicity in a Yang-Mills Quantum Theory

- Physics
- 1976

We propose a description of the vacuum in Yang-Mills theory and arrive at a physical interpretation of the pseudoparticle solution and the attendant violation of symmetries. The existence of…
