Study on the systematic effects on $b \to c$ inclusive semileptonic decays
/ Barone, Alessandro (U. Mainz, PRISMA) ; Elgaziari, Ahmed (Southampton U. ; U. Southampton (main)) ; Hashimoto, Shoji (KEK, Tsukuba ; Sokendai, Tsukuba) ; Hu, Zhi (KEK, Tsukuba) ; Jüttner, Andreas (Southampton U. ; U. Southampton (main) ; CERN) ; Kaneko, Takashi (KEK, Tsukuba ; Sokendai, Tsukuba) ; Kellermann, Ryan (KEK, Tsukuba)
We discuss the calculation of the inclusive semileptonic decay for the process $B_s \to X_c \, l ν_l$ using lattice QCD. [...]

First evidence of the decay $B^+ \to \pi^+ e^+ e^-$
/ LHCb Collaboration
The first evidence for the decay $B^+\to\pi^+ e^+ e^-$ is reported using proton-proton collision data recorded by the LHCb experiment at centre-of-mass energies of 7, 8 and 13 TeV, corresponding to an integrated luminosity of 9 fb$^{-1}$. [...]

Advances in photocathode development for PICOSEC Micromegas precise-timing detectors
/ Lisowska, M. (CERN ; Baskent U.) ; Guerra, F. (CERN ; INFN, Turin) ; Gurpinar, A. (CERN ; Middle East Tech. U., Ankara) ; Zavazieva, D. (Technion) ; Aleksan, R. (IRFU, Saclay) ; Aune, S. (IRFU, Saclay) ; Bortfeldt, J. (Munich U.) ; Breskin, A. (Weizmann Inst.) ; Brunbauer, F.M. (CERN) ; Brunold, M. (Pavia U. ; INFN, Pavia) et al.
The PICOSEC Micromegas detector is a precise-timing gaseous detector that combines a Cherenkov radiator, a semi-transparent photocathode and a Micromegas amplification stage, targeting time resolutions of tens of picoseconds for minimum ionising particles (MIPs). [...]

Constraining the trend of the $N = 50$ shell gap towards $^{100}$Sn with the masses of $^{96-98}$Cd
/ Lange, D. (Heidelberg, Max Planck Inst.) ; Atanasov, D. (SCK-CEN, Mol) ; Au, M. (CERN ; Mainz U.) ; Belley, A. (MIT) ; Benhatchi, M. (IJCLab, Orsay) ; Blaum, K.

We present the first determination of the $N = 50$ empirical shell gap at $Z = 48$ by precise mass measurements of the neutron-deficient cadmium isotopes $^{96-98}$Cd with the ISOLTRAP mass spectrometer at ISOLDE-CERN, including the first precise determination of the excitation energy of the $25/2^+$ isomer in $^{97}$Cd.
