A review of neutrino properties : Neutrino oscillations - a historical overview and its projection / Minkowski, Peter (Bern U. ; CERN)
In a first part neutrino properties are presented from the beginnings through the letter of Wolfgang Pauli on 4. December 1930 suggesting a new neutral fermion to the “Radioactive Ladies and Gentlemen” at a Conference in Tübingen, contributing to the first oscillation cycle, based on my review at the meeting “Neutrino Telescopes in Venice” in 2005.

Heavy ion physics at LHCb / Maurice, Émilie (Orsay, LAL ; Ecole Polytechnique) /LHCb
The LHCb detector, with its excellent momentum resolution and particle identification, is ideally suited for measuring heavy quark hadron and quarkonium production properties. Recent LHCb measurements of charmonium and open charm production in several configurations of proton-nucleus collisions are presented..

Search for magnetic monopoles with the MoEDAL forward trapping detector in 13 TeV proton-proton collisions at the LHC / Lionti, Anthony (Geneva U.) /MoEDAL
The MoEDAL experiment addresses a decades-old issue, the search for an elementary magnetic monopole, first theorised in 1931 by Dirac to explain electric charge quantisation. Since then it was showed that magnetic monopoles occur naturally in grand unified theories as solutions of classical equations of motion. [...]

Towards the first measurement of matter-antimatter gravitational interaction / Evans, C (Milan Polytechnic ; INFN, Milan) ; Aghion, S (Milan Polytechnic ; INFN, Milan) ; Amsler, C (Stefan Meyer Inst. Subatomare Phys.) ; Bonomi, G (U.

The AEgIS (Antimatter Experiment: Gravity, Interferometry, Spectroscopy) is a CERN based experiment with the central aim to measure directly the gravitational acceleration of antihydrogen. Antihydrogen atoms will be produced via charge exchange reactions which will consist of Rydberg-excited positronium atoms sent to cooled antiprotons within an electromagnetic trap. [...]

Search for $K^+\to \pi^+ \nu \bar \nu$ at NA62 / Aliberti, Riccardo (Mainz U.) /NA62
Flavour physics is one of the most powerful fields for the search of new physics beyond the Standard Model. The kaon sector with the rare decay $K^+\to \pi^+ \nu \bar \nu$ provides one of the cleanest and most promising channels. [...]

Integrated modeling of the beam formation and extraction in the Linac4 hydrogen negative ion source / Nishioka, S (Keio U.) ; Abe, S (Keio U.) ; Mattei, S (CERN) ; Lallement, J B (CERN) ; Kalvas, T (Jyvaskyla U.) ; Hatayama, A (Keio U.) ; Lettry, J (CERN)
In order to make the predictive simulation tools for the extracted beam current and emittance in the Linac4 H− ion source, we have launched the development of the integrated model for the H− ion beam formation and extraction process. More specifically, our 3D KEIO-Beam Formation and eXtraction (3D KEIO-BFX) is coupled with the NINJA, IBSIMU and TRAVEL. [...]

Charge breeding of CO$^{+}$ beams at REX-ISOLDE / Pitters, J (CERN) ; Breitenfeldt, M (CERN) ; Wenander, F (CERN)
The β+ emitter 11C is a possible treatment ion for hadron therapy owing to its excellent properties in PET imaging, which could be used for range verification during the treatment. A charge breeder is required to transform the molecular CO+ beam, coming from an ISOL-production stage (Isotope Separation OnLine), to Cn+ and to match it with the acceptance of the medical accelerator.

Plasma impedance prediction model and impedance matching by frequency tuning in radio frequency negative ion sources / Kobayashi, W (Keio U.) ; Nishida, K (Keio U.) ; Mattei, S (CERN) ; Lettry, J (CERN) ; Hatayama, A (Keio U.)
A radio frequency (RF) driven type hydrogen (H−) source is used as an injector of Linac4. The power transfer efficiency between the RF generator and the ion source plasma is one of the important parameters that determines the extracted H− beam current. [...]

Numerical analysis of ion dynamics in RF ICP discharge / Nishida, K (Keio U.) ; Mattei, S (CERN) ; Kobayashi, W (Keio U.) ; Lettry, J (CERN) ; Hatayama, A (Keio U.)
We have worked on the development of a particle-based numerical model of a hydrogen Radio Frequency (RF) Inductively Coupled Plasma (ICP). In the previous work, it has been shown that the model is able to simulate the E-to-H discharge mode transition, which is one of the distinct features of RF ICP. [...]
