The performance of the Advanced GAmma Tracking Array (AGATA) at GANIL is discussed, on the basis of the analysis of source and in-beam data taken with up to 30 segmented crystals. Data processing is described in detail. [...]

3D Printable Quark Puzzle: A Model to Build Your Own Particle Systems / McGinness, Lachlan (CERN) ; Dührkoop, Susanne (CERN) ; Woithe, Julia (CERN) ; Jansky, Alexandra (CERN)
There is an increasing emphasis on fundamental particles, including quarks, in the high school physics classroom. However, many teachers might not feel comfortable teaching particle physics because it is a highly abstract and complex topic, and there are few hands-on activities to help teachers bring it into the classroom. In 2010, Gettrust presented a two-dimensional quark puzzle, a physical manipulative that allowed students to discover the rules of the Standard Model of particle physics through inquiry. [...]

Entanglement and quantum tomography with top quarks at the LHC / Afik, Yoav (CERN) ; de Nova, Juan Ramón Muñoz (UCM, Madrid, Dept. Phys.)
Entanglement is a central subject in quantum mechanics. Due to its genuine relativistic behavior and fundamental nature, high-energy colliders are attractive systems for the experimental study of fundamental aspects of quantum mechanics. [...]

Has AMS-02 Observed Two-Component Dark Matter? / Profumo, Stefano (UC, Santa Cruz) ; Queiroz, Farinaldo (IIP, Brazil) ; Siqueira, Clarissa (IIP, Brazil)
There is convincing observational evidence for an increasing cosmic-ray positron-to-electron ratio at energies larger than $\sim 10$~GeV, at odds with expectations from secondary positron production. The most recent AMS-02 data exhibit an interesting spectral feature consisting of a bump at an energy around $300$~GeV followed by a drop around $\sim 800$~GeV. [...]

Measurements of hadronic resonance production with ALICE / Rosano, Antonina (Università degli Studi di Messina MIFT department and INFN Catania) /ALICE Collaboration
Short-lived hadronic resonances are an important tool to characterize the system formed both in elementary and heavy-ion collisions. Since they have a lifetime comparable to the fireball one, resonance measured yields may be affected by re-scattering and regeneration processes. [...]

Molecular Composition and Volatility of Nucleated Particles from $\alpha$-Pinene Oxidation between −50 °C and +25 °C / Ye, Qing (Carnegie Mellon U. (main)) ; Wang, Mingyi (Carnegie Mellon U. (main)) ; Hofbauer, Victoria (Carnegie Mellon U. (main)) ; Stolzenburg, Dominik (Vienna U.) ; Chen, Dexian (Carnegie Mellon U. (main)) ; Schervish, Meredith (Carnegie Mellon U.

Helsinki (main)) ; Brilke, Sophia (Vienna U.) et al.
We use a real-time temperature-programmed desorption chemical-ionization mass spectrometer (FIGAERO–CIMS) to measure particle-phase composition and volatility of nucleated particles, studying pure α-pinene oxidation over a wide temperature range (−50 °C to +25 °C) in the CLOUD chamber at CERN. Highly oxygenated organic molecules are much more abundant in particles formed at higher temperatures, shifting the compounds toward higher O/C and lower intrinsic (300 K) volatility. [...]

Higgs and BSM Studies at the LHC / Horváth, Dezso (Wigner RCP, Budapest ; Debrecen, Inst. Nucl. Res.) /CMS Collaboration
The discovery and study of the Higgs boson at the Large Hadron Collider of CERN has proven the validity of the Brout–Englert–Higgs mechanism of mass creation in the standard model via spontaneous symmetry breaking. The new results obtained by the ATLAS and CMS Collaborations at the LHC show that all measured cross-sections agree within uncertainties with the predictions of the theory. [...]

Exploring the energy frontier with deep inelastic scattering at the LHC / Brüning, Oliver (CERN) ; Klein, Max (U. Liverpool (main)) /LHeC Collaboration ; PERLE Collaboration
A proposal is described for complementing the intense, high energy proton and ion beams of the Large Hadron Collider (LHC) with a novel electron energy recovery linac (ERL) to provide a next generation electron-hadron collider facility of more than 1 TeV center-of-mass energy. This Large Hadron Electron Collider (LHeC) will substantially extend the kinematic range covered by the first ep collider, HERA, and surpass its luminosity by a factor of several hundreds. [...]

Long-range propagation of ultrafast ionizing laser pulses in a resonant nonlinear medium / Demeter, G. (Wigner RCP, Budapest) ; Moody, J.T. (Munich, Max Planck Inst.) ; Aladi, M. (Wigner RCP, Budapest) ; Bachmann, A.-M. (Munich, Max Planck Inst.) ; Batsch, F. (Munich, Max Planck Inst.) ; Braunmüller, F. (Munich, Max Planck Inst.) ; Djotyan, G.P. (Wigner RCP, Budapest) ; Fedosseev, V. (CERN) ; Friebel, F. (CERN) ; Gessner, S. et al.
We study the propagation of 0.05-1 TW power, ultrafast laser pulses in a 10 meter long rubidium vapor cell. The central wavelength of the laser is resonant with the $D_2$ line of rubidium and the peak intensity in the $10^{12}-10^{14} ~W/cm^2$ range, enough to create a plasma channel with single electron ionization [...]

Characterization of ALPIDE silicon sensors with inclined tracks / Kushpil, Svetlana (Rez, Nucl. Phys. Inst.) /ALICE Collaboration
The upgrade of the ALICE Inner Tracking System (ITS) aims at improving the capabilities of ALICE in terms of read-out rate as well as track pointing resolution and track finding efficiency, especially for particleswith low transverse momenta. The new ITS will be a low material budget detector with high granularity and read-out speed. [...]
