 Nano-Games for Cultural Venues: the HEAL game / Rompa, Jenny (Peloponnese U.) ; Lepouras, Georgios (Peloponnese U.) ; Antoniou, Angeliki (Peloponnese U.) ; Pequenão, Joao (CERN) Many are the times when visitors leave an exhibition without a clue about its message. In an effort to eliminate this phenomenon, museums, institutes and organisations (MIOs) adopt more attractive, engaging and fun content to provide a high quality and fast learning experience.

 The Latest Results from the Alpha Magnetic Spectrometer / Kounine, Andrei (MIT) /AMS Collaboration The Alpha Magnetic Spectrometer (AMS) is a 15-nation project on the International Space Station (ISS). Following a 16-year period of construction and testing and a precursor flight on the Space Shuttle in 1998, AMS was installed on the ISS on May 19, 2011.

 Precision Electroweak Measurements at FCC-ee / Locci, Elizabeth (IRFU, Saclay) /FCC Design Study Group With the discovery of the Higgs boson at the LHC in 2012, all fundamental parameters of the Standard Model Theory (SMT) have been experimentally measured. Then the global fits of the electroweak sector provide a powerful test of the internal consistency of the SMT.

 Probability-related naïve ideas across physics topics / Hull, Michael M (Vienna U.) ; Jansky, Alexandra (Vienna U. ; CERN) ; Hopf, Martin (Vienna U.) In this literature review, we survey student naïve ideas (frequently referred to as ‘misconceptions’) that plausibly relate, at least in part, to difficulty in understanding probability. We collected diverse naïve ideas from a range of topics in physics: Non-linear Dynamics; Cosmology; Thermal Physics; Atomic, Nuclear, and Particle Physics; Elementary Particle Physics; Quantum Physics; and Measurements and Uncertainties.

 Collective dynamics in relativistic nuclear collisions studied with ALICE at the LHC / Kawęcka, Anna (Warsaw U. of Tech.) /ALICE Collaboration ALICE is a detector designed to study strongly interacting matter at extreme temperatures and energy densities, where the quark-gluon plasma (QGP) is formed, but it also allows one to perform unique measurements in proton– proton and proton–lead collisions. In these proceedings, we present a selected set of correlation measurements done by ALICE, in both heavy-ion collisions and in small collision systems. [...] 2020 - 7 p. - Published in : Proc.

 Design Study of X-band High Efficiency Klystrons for CLIC / Cai, Jinchi (Lancaster U. ; CERN) ; Syratchev, Igor (CERN) The design of two X-band high efficiency (HE) Klystrons are presented in this paper. Based on Core Oscillation Method (COM) and coupled-cell output structure topology, 8MW Klystron for Xbox test stand can yield 58% output efficiency with beam perveance of 1.6uP.

 Two-particle angular correlations of mesons and baryons measured in ALICE / Głuchowski, Krystian (Warsaw U. of Tech.) /ALICE Collaboration ALICE is one of the four main experiments at the Large Hadron Collider (LHC), mainly focused on heavy-ion collisions in which the Quark-Gluon Plasma (QGP) could be produced. One of the tools to study the properties of the QGP and the process of hadron production are two-particle angular correlations. [...] 2020 - 7 p. - Published in : Proc.

 A new anomaly observed in $^4$He supporting the existence of the hypothetical X17 particle / Krasznahorkay, A J (KLTE-ATOMKI) ; Csatlós, M (KLTE-ATOMKI) ; Csige, L (KLTE-ATOMKI) ; Gulyás, J (KLTE-ATOMKI) ; Koszta, M (KLTE-ATOMKI) ; Szihalmi, B (KLTE-ATOMKI) ; Timár, J (KLTE-ATOMKI) ; Firak, D S (Debrecen U.) ; Nagy, Á (Debrecen U.) ; Sas, N J (Debrecen U.) et al. Recently, we observed an anomalous peak-like excess of internal $e^+e^-$ pairs at around 140° for the M1 transition depopulating the 18.15 MeV isoscalar $1^+$ state in $^8$Be. The deviation from the theoretical prediction can be described by GEANT simulations assuming the creation and subsequent decay of a new, light boson with a mass of 16.7 MeV/$c^2$.

 Latest results on rare kaon decays from the NA48/2 experiment @CERN / NA48/2 Collaboration The NA48/2 experiment at CERN reports the first observation of the $K^± → π^±π^0e^+e^−$ decay from an exposure of $1.7 × 10^{11}$ charged kaon decays recorded in 2003–2004. A sample of 4919 candidates with 4.9% background contamination allows the determination of the branching ratio in the full kinematic region. [...] 2020 - 9 p. - Published in : Int. J. Mod. Phys.
