 Low dose rate $^{60}$Co facility in Zagreb / Roguljic, Matej (Boskovic Inst., Zagreb) ; Starodumov, Andrey (Boskovic Inst., Zagreb) ; Karadzhinova-Ferrer, Aneliya (Boskovic Inst., Zagreb) ; Ferencek, Dinko (Boskovic Inst., Zagreb) ; Ahmed, Ahmed Abdirashid (Odense U.) ; Jara-Casas, Luis Miguel (CERN) The Co-60 irradiation facility at Ruđer Bošković Institute in Zagreb allows for gamma irradiation in a large range of doses from a maximum of 30kGy/h down to 30Gy/h. Recently, a setup for the radiation tolerance study of readout electronics has been built inside the irradiation chamber.

 $CP$ violation and mixing in charm decays at LHCb / Schubiger, Maxime (Nikhef, Amsterdam) /LHCb Collaboration The size of $CP$ violation allowed for by the Standard Model is orders of magnitude too small to explain our matter-dominated universe. Processes from physics beyond the Standard Model could enhance this violation and explain the observed asymmetry between matter and antimatter.The charm sector is a relevant probe to search for New Physics processes and is complementary to other searches in the kaon and $B$ systems.

 Lepton flavour universality tests in rare $b\to s\ell\ell$ decays / Langenbruch, Christoph (RWTH Aachen U.) /LHCb Collaboration The coupling of the electroweak gauge bosons in the Standard Model is lepton flavour universal. Rare semileptonic $b\to s\ell^+\ell^-$ decays constitute sensitive probes for New Physics models that violate lepton flavour universality.

 Angular analysis of $\mathrm{B}\to\mathrm{K}^{(*)}\mu\mu$ decays at CMS / Boletti, Alessio (INFN, Padua ; Padua Observ.) /CMS Collaboration The flavour changing neutral current decays are interesting probes for new physics searches. The angular distributions of $b \to s \ell^+ \ell^-$ transition processes of both $\mathrm{B}^0 \to \mathrm{K}^{*0} \mu^ +\mu^-$ and $\mathrm{B}^{+} \to \mathrm{K}^{+} \mu^+\mu^-$ decays are studied using a sample of proton-proton collisions at $\sqrt{s} = 8~\mathrm{TeV}$ collected with the CMS detector at the LHC, corresponding to an integrated luminosity of $20.5~\mathrm{fb}^{-1}$.

 Recent results in kaon physics / Kucerova, Zuzana (Comenius U.) /NA62 Collaboration A review of the present experimental status of the $K \to \pi \nu \overline{\nu}$ ($K_{\pi \nu \nu}$) and other kaon decay analyses at experiments NA62 (CERN) and KOTO (J-PARC) is given. The $K_{\pi \nu \nu}$ decay is one of the best candidates among the rare meson decays for indirect searches for new physics in the mass ranges complementary to those accessible by current accelerators.

 Heavy flavour production at LHCb / Rotondo, Marcello (Frascati) /LHCb Collaboration The measurements of heavy flavour production in pp collisions provide crucial inputs to study both perturbative and non-perturbative quantum chromodynamics. Moreover these measurements allow to improve the precision on the study of heavy hadron decays.LHCb has a large program of studies of heavy flavour production and it has, compared with other experiments at the LHC, the unique feature to cover the very forward region.In this paper the most recent results on the quarkonia production and fragmentation fractions for various kind of heavy hadrons are presented..

 CMS studies in heavy flavor production / Galanti, Mario (Rochester U.) /CMS Collaboration In these proceedings I shortly describe some of the most recent results published by the CMS Collaboration in the field of heavy flavor production. In particular, I discuss measurements of open heavy flavor and quarkonium production cross sections, and of heavy baryon polarization at $\sqrt{s}=7$, $8$, and $13\,\mathrm{TeV}$..

 Charmless $b$-hadron decays at LHCb / O'Hanlon, Daniel (INFN, Bologna) /LHCb Collaboration Violation of charge-parity ($C\!P$) symmetry in the Standard Model is driven by a single global phase, however manifestations of $C\!P$ violating quantities are often non-trivial due to the role of the strong interaction in generating observable $C\!P$ violation effects. Here we explore how the role of the strong phase in $B^+ \rightarrow \pi^+\pi^+\pi^-$ decays, described by the intermediate resonance structure and final-state rescattering effects, governs the manifestation of large $C\!P$ violation.

 FCNC in top quark transitions in ATLAS / Daneri, Florencia M (Buenos Aires U.) /ATLAS Collaboration There are many flavour changing neutral current (FCNC) searches ongoing that focus on the top quark sector using pp collisions data taken with the ATLAS detector at the LHC. Several cou- plings and final states are being investigated based on different analysis strategies.

 Radiative decays at LHCb / Krokovny, Pavel (Novosibirsk State U. ; Novosibirsk, IYF) The radiative decay $\Lambda _{b}^{0}$ $\rightarrow$  $\Lambda ^{0}$ $\gamma$ is observed for the first time using a data sample of proton-proton collisions corresponding to an integrated luminosity of 1.7 fb$^{-1}$ collected by the LHCb experiment at a center-of-mass energy of 13 TeV. Its branching fraction is measured to be B($\Lambda _{b}^{0}$ $\rightarrow$  $\Lambda ^{0}$ $\gamma$) = (7.1 $\pm$ 1.5 $\pm$  0.6 $\pm$  0.7) 10$^{-6}$, where the quoted uncertainties are statistical, systematic and systematic from external inputs, respectively.A time-dependent analysis of the $B_{S}^{0} \rightarrow \phi \gamma$  decay rate is performed to determine the CP-violating observables $\mathit{S}\phi \gamma$ and $\mathit{C}\phi \gamma$, and the mixing-induced observable Adelta.
