Beyond the SM searches at the LHC: Little Higgs models and Effective Field Theory
Hamburg : Verlag Deutsches Elektronen-Synchrotron, DESY-THESIS, 117 pp. (2018) [10.3204/PUBDB-2018-01793] = Dissertation, Universität Hamburg, 2018  GO
In this thesis, we discuss two different approaches to physics beyond the Standard Model.First, we study a model-independent Effective Field Theory formalism. In particular, wefocus on bosonic CP-even six-dimensional operators. [...]

Attosecond time–energy structure of X-ray free-electron laser pulses
The time–energy information of ultrashort X-ray free-electron laser pulses generated by the Linac Coherent Light Source is measured with attosecond resolution via angular streaking of neon 1s photoelectrons. The X-ray pulses promote electrons from the neon core level into an ionization continuum, where they are dressed with the electric field of a circularly polarized infrared laser. [...]

Multidimensional photoemission spectroscopy—the space-charge limit
Photoelectron spectroscopy, especially at pulsed sources, is ultimately limited by the Coulomb interaction in the electron cloud, changing energy and angular distribution of the photoelectrons. A detailed understanding of this phenomenon is crucial for future pump–probe photoemission studies at (x-ray) free electron lasers and high-harmonic photon sources. [...]

Silica Aerogel Radiators for Bunch Length Measurements
Cherenkov radiators based on silica aerogel are used to measure the electron bunch length at the photo injector test facility at DESY Zeuthen (PITZ). The energy range of those electrons is 4–5 MeV. [...]

A search for resonant absorption of the solar axion by $^{83}\rm{Kr}$ nuclei was performed using the proportional counter installed inside the low-background setup at the Baksan Neutrino Observatory. The obtained model independent upper limit on the combination of isoscalar and isovector axion-nucleon couplings $|g_3-g_0|\leq 8.4\times 10^{-7}$ allowed us to set the new upper limit on the hadronic axion mass of $m_{A}\leq 65$ eV (95\% C.L.) with the generally accepted values $S$=0.5 and $z$=0.56..

We discuss the Oscillating Resonant Group AxioN (ORGAN) experiment, a high mass axion haloscope hosted at the University of Western Australia (UWA). The path-finding experiment placed limits in a narrow frequency range around 26 GHz, and the future searches, which will be enabled by novel resonator designs based on dielectric structures, will focus on wider mass ranges with increased sensitivity.
