Summary
Born-Infeld modification of Yang-Mills theory creates novel particlelike solutions. This approach breaks scale invariance, leading to new classical glueballs resembling Bartnik-McKinnon solutions.
Area of Science:
- Theoretical High-Energy Physics
- Quantum Field Theory
Background:
- Standard Yang-Mills theory lacks particlelike solutions.
- Scale invariance is a key feature of standard Yang-Mills theory.
Purpose of the Study:
- To investigate particlelike solutions in modified Yang-Mills theory.
- To explore the consequences of Born-Infeld nonlinearity.
Main Methods:
- Modification of the quadratic Yang-Mills action with Born-Infeld nonlinearity.
- Analysis of classical solutions arising from the modified action.
Main Results:
- The Born-Infeld modification allows for classical particlelike solutions.
- Scale invariance is broken by the Born-Infeld nonlinearity.
- New classical glueballs with sphaleronic nature were found.
Conclusions:
- Born-Infeld modification offers a route to new classical solutions in Yang-Mills theory.
- These solutions share similarities with Bartnik-McKinnon solutions, suggesting deeper connections.
