Non-abelian self-dual strings in six dimensions from four dimensional 1/2-BPS monopoles (2014)
Journal Article
Chu, C. (2014). Non-abelian self-dual strings in six dimensions from four dimensional 1/2-BPS monopoles. Nuclear Physics B, 882, 289-302. https://doi.org/10.1016/j.nuclphysb.2014.03.006

We explain a new construction of self-dual string solutions to the non-abelian two-form self-duality equation proposed in [1]. This class of self-dual strings is determined by the BPS monopoles in four-dimensions and the self-dual string charge is gi...

SUSY breaking by a metastable ground state: Why the early universe preferred the non-supersymmetric vacuum (2007)
Journal Article
Abel, S. A., Chu, C., Jaeckel, J., & Khoze, V. V. (2007). SUSY breaking by a metastable ground state: Why the early universe preferred the non-supersymmetric vacuum. Journal of High Energy Physics, 2007(01), https://doi.org/10.1088/1126-6708/2007/01/089

Supersymmetry breaking in a metastable vacuum is re-examined in a cosmological context. It is shown that thermal effects generically drive the Universe to the metastable minimum even if it begins in the supersymmetry-preserving one. This is a generic...

A note on string interaction on the pp-wave background (2004)
Journal Article
Chu, C., Khoze, V., Petrini, M., Russo, R., & Tanzini, A. (2004). A note on string interaction on the pp-wave background. Classical and Quantum Gravity, 21(8), 1999-2009. https://doi.org/10.1088/0264-9381/21/8/006

We consider type IIB string interaction on the maximally supersymmetric pp-wave background and discuss how the bosonic symmetries of the background are realized. This analysis shows that there are some interesting differences with respect to the flat... Read More about A note on string interaction on the pp-wave background.

Correspondence between the 3-point BMN correlators and the 3-string vertex on the pp-wave (2003)
Journal Article
Chu, C., & Khoze, V. (2003). Correspondence between the 3-point BMN correlators and the 3-string vertex on the pp-wave. Journal of High Energy Physics, 2003(04), Article 014. https://doi.org/10.1088/1126-6708/2003/04/014

The PP-wave/SYM proposal in its original form emphasizes a duality relation between the masses of the string states and the anomalous dimensions of the corresponding BMN operators in gauge theory, the mass-dimension type duality. In this paper, we gi... Read More about Correspondence between the 3-point BMN correlators and the 3-string vertex on the pp-wave.

Noncommutative D-brane and open string in pp-wave background with B-field (2002)
Journal Article
Chu, C., & Ho, P. (2002). Noncommutative D-brane and open string in pp-wave background with B-field. Nuclear Physics B, 636(1-2), 141-158. https://doi.org/10.1016/s0550-3213%2802%2900360-7

The open string ending on a D-brane with a constant B-field in a pp-wave Ramond–Ramond background is exactly solvable. The theory is controlled by three dimensionful parameters: α′, the mass parameter (RR background times the lightcone momentum) and...

Hermitian Analyticity, IR/UV Mixing and Unitarity of Noncommutative Field Theories (2002)
Journal Article
Chu, C., Lukierski, J., & Zakrzewski, W. (2002). Hermitian Analyticity, IR/UV Mixing and Unitarity of Noncommutative Field Theories. Nuclear Physics B, 632(1-3), 219-239. https://doi.org/10.1016/s0550-3213%2802%2900216-x

The IR/UV mixing and the violation of unitarity are two of the most intriguing aspects of noncommutative quantum field theories. In this paper the relation between these two phenomena is explained and established in an explicit form. We start out by...

Three-point functions in N = 4 Yang-Mills theory and pp-waves (2002)
Journal Article

Recently it has been proposed that the coefficient of the three-point function of the BMN operators in = 4 supersymmetric Yang-Mills theory is related to the three-string interactions in the pp-wave background. We calculate three-point functions of t... Read More about Three-point functions in N = 4 Yang-Mills theory and pp-waves.
