The use of Effective Field Theories (EFTs) in the search of New Physics is becoming more and more important given the lack of clear experimental signs of BSM physics. In particular, the Standard Model EFT (SMEFT) has become one of the most popular choices. [...]

Laser-plasma acceleration[1], among others[2,3],promises to be a powerful technology for driving future compact light sources. LUX, which is operated by University of Hamburg,is such a laser-plasma accelerator [...]

The LUX laser-plasma-accelerator [1], built in close collaboration of the University of Hamburg and DESY, isdesigned to provide plasma electron beams with enhanced stability as a driver for future compact light sources.After significant in-house development of the driving 200 TW ANGUS laser system, the laser has reached anoperational stability, that enables us to repeatedly demonstrate day-long operation of the laser-plasma acceleratorwith several 10k consecutive electron beams and high availability. The electron beam quality is sufficient to drivea miniature undulator, generating synchrotron-type undulator radiation at wavelengths well below 9 nm.We report on experimental results of the long-term stability of the ANGUS laser system with sub 2% energystability over a full day, and pulse duration stability on the 1% level, that have been enabled through activefeedback loops at various stages within the amplification chain [...]

RNO-G targets neutrino energies above 10 PeV. It uses the detection of the produced radio signals from the particle showers due to highly energetic neu- trinos interacting in the ice. [...]

Deployment of the Radio Neutrino Observatory Greenland (RNO-G) is planned to start in 2020 at Summit Station, Greenland. In the next few years, thirty-five stations will be deployed and RNO-G will also act as a pathfinder for IceCube-Gen2. [...]

The luminosity measurement of the CMS experiment is calibrated under special beam conditions with beam separation scans called Van der Meer (VdM) scans. In a VdM scan, the two proton beams are separated transversely and moved in steps across each other. [...]

Tomographic methods for the imaging of complex structures are widely used in medical, industrial and scientific applications. Recently, we proposed a new imaging modality based on the measurement of the trajectory of electrons traversing a sample under test with electron momenta in the range of a few hundred MeV/$c$ up to several GeV/$c$.

Architecture of alkyl substituents and π-π interactions between aromatic parts are the key factors governing self-assembly and crystallization of alkyl-bearing aromatic molecules or macromolecules [1,2]. It was demonstrated that interactions between alkyl chains of N-substituted aromatic diimide derivatives (ADI) and poly(3-hexylthiophene) (P3HT) may drive formation of different crystal structures in P3HT:ADI blends [3,4].
