Experimental Evidence for Common Driving Effects in Low-Energy Fission from Sublead to Actinides / Schmitt, C (Strasbourg, IPHC) ; Lemasson, A (GANIL) ; Schmidt, K H (Erzhausen, Germany) ; Jhingan, A (IUAC, New Delhi) ; Biswas, S (GANIL) ; Kim, Y H (Laue-Langevin Inst.) ; Ramos, D (GANIL) ; Andreyev, A N (York U., England ; JAERI, Tokai ; CERN) ; Curien, D (Strasbourg, IPHC) ; Ciemala, M (Cracow, INP) et al.
Isotopic distributions of fragments from fission of the neutron-deficient $^{178}$Hg nuclide are reported. This experimental observable is obtained for the first time in the region around lead using an innovative approach based on inverse kinematics and the coincidence between the large acceptance magnetic spectrometer VAMOS++ and a new detection arm close to the target.

$^{178}\mathrm{Hg}$ and asymmetric fission of neutron-deficient pre-actinides / Jhingan, A. (IUCAA, Pune) ; Schmitt, C. (Strasbourg, IPHC) ; Lemasson, A. (GANIL) ; Biswas, S. (GANIL) ; Kim, Y.H.

Fission at low excitation energy is an ideal playground to probe the impact of nuclear structure on nuclear dynamics. While the importance of structural effects in the nascent fragments is well-established in the (trans-)actinide region, the observation of asymmetric fission in several neutron-deficient pre-actinides can be explained by various mechanisms.

Proton reconstruction with the CMS-TOTEM Precision Proton Spectrometer / CMS and TOTEM Collaboration
The Precision Proton Spectrometer (PPS) of the CMS and TOTEM experiments collected 107.7 fb$ ^{-1} $ in proton-proton (pp) collisions at the LHC at 13 TeV (Run 2). This paper describes the key features of the PPS alignment and optics calibrations, the proton reconstruction procedure, as well as the detector efficiency and the performance of the PPS simulation.

Search for $^{22}$Na in novae supported by a novel method for measuring femtosecond nuclear lifetimes / Fougères, Chloé (GANIL ; Argonne, PHY) ; de Oliveira Santos, François (GANIL) ; José, Jordi (Barcelona U. ; Barcelona, IEEC) ; Michelagnoli, Caterina (Laue-Langevin Inst.) ; Clément, Emmanuel (GANIL) ; Kim, Yung Hee (GANIL ; IBS, Daejeon, CENS) ; Lemasson, Antoine (GANIL) ; Guimarães, Valdir (Sao Paulo U.) ; Barrientos, Diego (CERN) ; Bemmerer, Daniel (HZDR, Dresden) et al.
Classical novae are thermonuclear explosions in stellar binary systems, and important sources of $^{26}$Al and $^{22}$Na. While gamma rays from the decay of the former radioisotope have been observed throughout the Galaxy, $^{22}$Na remains untraceable. [...]

Measurements of light-by-light scattering (LbL, $ \gamma\gamma\to\gamma\gamma $) and the Breit-Wheeler process (BW, $ \gamma\gamma\to\mathrm{e}^+\mathrm{e}^- $) are reported in ultraperipheral PbPb collisions at a centre-of-mass energy per nucleon pair of 5.02 TeV. [...]

A pioneering machine-learning-based flavor-tagging algorithm combining same-side and opposite-side tagging is used to obtain the equivalent of 27 500 tagged $ \mathrm{B}_{s}^{0} \to \mathrm{J}/\psi\,\phi(1020) $ decays from pp collisions at $ \sqrt{s} = $ 13 TeV, collected by the CMS experiment and corresponding to an integrated luminosity of 96.5 fb$^{-1}$.
