Welcome to my website. My name is Christian Spethmann, I am currently working as a Postdoc at Boston University. My research focus is on elementary particle theory, and more specifically on the collider phenomenology of Beyond the Standard Model physics. On this website you will find my on-line CV, a list of my papers, and some recent talks.

I was born in Germany, where my education as a physicist started at the University of Münster. For my Diplom thesis I applied Chiral Perturbation Theory to lattice simulations with dynamic fermions. Specifically, I investigated implications of the "Twisted Mass" scheme.

The next step of my career was Ithaca, NY. As a graduate student at Cornell University I worked on a broad range of subjects in high energy phenomenology. Together with my Ph.D. advisor Maxim Perelstein I explored fine tuning and experimental constraints in the minimal supersymmetric standard model, identifying the most promising regions of its parameter space. I also worked on a UV completion of Little Higgs theories, collaborated with CMS experimentalists on a detector study for model discrimination, and co-authored a paper on accelerator physics.

Since September 2009 I have worked as a Postdoc at Boston University. Together with Martin Schmaltz, I investigated signatures of potential W' bosons at the early LHC, clarifying that new gauge bosons with right-handed couplings are the most promising search targets. I then investigated if charged gauge bosons could cause the Tevatron ttbar forward-backward asymmetry, and concluded that no perturbative description of such physics can be reconciled with gauge symmetry and neutral resonance searches. More recently, I have worked on boosted objects, multijet signatures of axigluons that would explain the Tevatron forward-backward asymmetry, and on Standard Model predictions for diphoton production.
