During the summer of 2021, young scientists from more than 13 different countries worked together, connecting in virtual meetings two times a day for scientific projects within the CMS particle physics group at DESY..

We present a study of the LHC (and HL-LHC) potential towards a precise determination of the gluon parton distribution function of the proton at intermediate Bjorken-$x$ from measurements of Drell-Yan production. To this extent, we exploit a clean and theoretically well predicted observable: the Drell-Yan lepton angular coefficient $A_0$, associated with the longitudinal polarization of the Z boson. [...]

These proceedings report on recent analyses of the Higgs sector by the ATLAS and CMS experiments at the Large Hadron Collider. Most analyses are based on the dataset taken during the LHC Run2, corresponding to an integrated luminosity of close to 140 fb−1 per experiment. [...]

Data from the LHC at 7, 8, and 13 TeV have so far yielded no evidence for new particles beyond the 125 GeV Higgs boson, in particular, there have been no signs of SUSY. However, the complementary nature of physics with e$^{+}$e$^{-}$ collisions still offers many interesting scenarios in which SUSY can be discovered at the ILC. [...]

Dielectric laser driven particle acceleration (DLA) is one of the candidates for novel high-gradient technologies to reduce the footprint of large scale particle acceleration facilities. On the other hand these devices can be used to interact with the particle beams of state-of-the-art photon science machines, especially with FELs, to manipulate the longitudinal phase space in a compact and cost effective way.

In the recent years, the production, application and research of commercially pure titanium, titanium alloys and titanium aluminides have advanced considerably. In this keynote paper, information is provided on important achievements in the German titanium industry, governmental and non-governmental research organisations and universities. [...]

Due to their outstanding mechanical properties, excellent corrosion resistance and biocompatibility titanium and titanium alloys are the first choice for medical engineering products. Alloys currently used for implant applications are Ti-6Al-4V (ELI) and Ti-6Al-7Nb. [...]
