Hearing the signal of dark sectors with gravitational wave detectors (2016)
Journal Article
Jaeckel, J., Khoze, V. V., & Spannowsky, M. (2016). Hearing the signal of dark sectors with gravitational wave detectors. Physical Review D, 94(10), Article 103519. https://doi.org/10.1103/physrevd.94.103519Motivated by advanced LIGO (aLIGO)’s recent discovery of gravitational waves, we discuss signatures of new physics that could be seen at ground- and space-based interferometers. We show that a first-order phase transition in a dark sector would lead... Read More about Hearing the signal of dark sectors with gravitational wave detectors.
Jet activity as a probe of diphoton resonance production (2016)
Journal Article
Harland-Lang, L., Khoze, V., Ryskin, M., & Spannowsky, M. (2016). Jet activity as a probe of diphoton resonance production. The European Physical Journal C, 76, Article 623. https://doi.org/10.1140/epjc/s10052-016-4471-4We explore the method of using the measured jet activity associated with a high-mass resonance state to determine the corresponding production modes. To demonstrate the potential of the approach, we consider the case of a resonance of mass MR decayin... Read More about Jet activity as a probe of diphoton resonance production.
Neutrino jets from high-mass WR gauge bosons in TeV-scale left-right symmetric models (2016)
