BPS solutions for generalised Wess-Zumino models and their applications (2019)
Journal Article
Abel, S., Bonnefoy, Q., & Chowdhury, D. (2019). BPS solutions for generalised Wess-Zumino models and their applications. Journal of High Energy Physics, 2019(10), Article 242. https://doi.org/10.1007/jhep10%282019%29242

We present BPS solutions to a general class of Wess-Zumino models which ex- tend previous results in the literature. We discuss their relation to amplitudes on threshold, and their application to scalar domain walls in Supersymmetric QCD. We also fin...

Stability and Vacuum Energy in Open String Models with Broken Supersymmetry (2019)
Journal Article
Abel, S., Dudas, E., Lewis, D., & Partouche, H. (2019). Stability and Vacuum Energy in Open String Models with Broken Supersymmetry. Journal of High Energy Physics, 2019(10), Article 226. https://doi.org/10.1007/jhep10%282019%29226

We construct type I string models with supersymmetry broken by compactifi- cation that are non-tachyonic and have exponentially small effective potential at one-loop. All open string moduli can be stabilized, while the closed string moduli remain mas... Read More about Stability and Vacuum Energy in Open String Models with Broken Supersymmetry.

Out-of-the-box baryogenesis during relaxation (2019)
Journal Article
Abel, S., Gupta, R., & Scholtz, J. (2019). Out-of-the-box baryogenesis during relaxation. Physical Review D, 100, Article 015034. https://doi.org/10.1103/physrevd.100.015034

We show that spontaneous baryogenesis occurs automatically in relaxion models if the reheating temperature is larger than the weak scale, provided the Standard Model fields are charged under the U(1) of which the relaxion is a pseudo-Nambu-Goldstone...

UV completion on the worldline (2019)
Journal Article
Abel, S., & Dondi, N. A. (2019). UV completion on the worldline. Journal of High Energy Physics, 2019(7), Article 90. https://doi.org/10.1007/jhep07%282019%29090

A framework for UV completing particle theories is proposed, based on the worldline formalism, which is equivalent to weighting all sums over histories with a propertime dependent measure that has a smallest proper-time. We deduce a criterion to avoi... Read More about UV completion on the worldline.

Dual renormalization group flows in 4D (2019)
Journal Article
Abel, S., Bajc, B., & Sannino, F. (2019). Dual renormalization group flows in 4D. Physical Review D, 99(6), Article 065001. https://doi.org/10.1103/physrevd.99.065001

We present a prescription for using the a central charge to determine the flow of a strongly coupled supersymmetric theory from its weakly coupled dual. The approach is based on the equivalence of the scale-dependent a parameter derived from the four... Read More about Dual renormalization group flows in 4D.

Complete asymptotically safe embedding of the standard model (2019)
Journal Article
Abel, S., Mølgaard, E., & Sannino, F. (2019). Complete asymptotically safe embedding of the standard model. Physical Review D, 99(3), Article 035030. https://doi.org/10.1103/physrevd.99.035030

We present and discuss the “Tetrad Model”, a large color/flavor embedding of the Standard model which has an interacting ultraviolet fixed point. It is shown that its extended-Pati-Salam symmetry is broken radiatively via the Coleman-Weinberg mechani... Read More about Complete asymptotically safe embedding of the standard model.
