Long-range correlations in low-multiplicity pp collisions at $\sqrt{s}=13\,\mathrm{TeV}$ / Parkkila, J.E.
In these proceedings, the measurements of the long-range near-side yields of charged hadrons in low-multiplicity proton--proton collisions at \thirteen are presented. [...]

Ultra narrowband detection scheme for dark photon / axion around 30 GHz / Miyazaki, A (Uppsala U.) ; Lofnes, T (Uppsala U.) ; Caspers, F (ESI, Archamps ; CERN) ; Spagnolo, P (INFN, Pisa) ; Jelonnek, J (KIT, Karlsruhe) ; Ruess, T (KIT, Karlsruhe) ; Steinmann, J L (KIT, Karlsruhe) ; Thumm, M (KIT, Karlsruhe)
We demonstrated that ultra narrowband filtering at 30 GHz dramatically enhances the signal-to-noise ratio to search for dark matter candidates which couple to millimeter waves. [...]

Electromagnetic high-frequency gravitational wave detection / Domcke, Valerie (CERN)
Ultra-high frequency gravitational waves in the MHz to THz regime promise a unique possibility to probe the very early universe, particle physics at very high energies and exotic astrophysical objects - but achieving the sensitivity required for detection is an immense challenge. [...]

A dynamic beam window for coupling accelerator and reactor core in an ADS / Caspers, Fritz (CERN) ; Mueller, Alex C. (ACM Consult GmbH, Mainz)
During the many fruitful discussions and presentations at this EUCARD2-workshop we all were once more reminded of the respective technical short comings of the two solutions bringing an intense proton-beam on a molten-lead spallation target housed inside a fuel-loaded reactor. These are namely the window-less target solution where the accelerator is completely unprotected from accidentally back-streaming target material or the window solution with it’s inherent danger of catastrophic failure. [...]

Beyond Tree Level with Solar Neutrinos: Towards Measuring the Flavor Composition and CP Violation / Brdar, Vedran (CERN) ; Xu, Xun-Jie
After being produced as electron neutrinos ($\nu_e$), solar neutrinos partially change their flavor to $\nu_{\mu}$ and $\nu_{\tau}$ en route to Earth. [...]

Symmetries and Selection Rules: Optimising Axion Haloscopes for Gravitational Wave Searches / Domcke, Valerie (CERN) ; Garcia-Cely, Camilo (Valencia U., IFIC) ; Lee, Sung Mook ; Rodd, Nicholas L. (CERN)
In the presence of electromagnetic fields, both axions and gravitational waves (GWs) induce oscillating magnetic fields: a potentially detectable fingerprint of their presence. [...]

Evidence for the decays $B^{0}\rightarrow\bar{D}^{(*)0}\phi$ and updated measurements of the branching fractions of the $B^{0}_{s}\rightarrow\bar{D}^{(*)0}\phi$ decays / LHCb Collaboration
Evidence for the decays $B^{0}\rightarrow\bar{D}^{0}\phi$ and $B^{0} \rightarrow \bar{D}^{*0}\phi$ is reported with a significance of 3.6$\,\sigma$ and 4.3$\,\sigma$, respectively [...]
