The 100 Tm superconducting synchrotron SIS100 is the main accelerator of the international Facility for Antiproton and Ion Research (FAIR) currently under advanced construction in Darmstadt, Germany. The SIS100 dipole circuit which creates the magnetic field required to bend the beam, consists of 108 dipoles distributed over six arc sections of the ring. [...]

The LHCb upgrade I / LHCb Collaboration
The LHCb upgrade represents a major change of the experiment. The detectors have been almost completely renewed to allow running at an instantaneous luminosity five times larger than that of the previous running periods. [...]

First measurement of the $C\!P$-violating phase in ${{B} ^0_{s}} \!\rightarrow {{J /\psi }} (\rightarrow e ^+e ^-$)$\phi $ decays / LHCb Collaboration
A flavour-tagged time-dependent angular analysis of $B^0_s\to J/\psi\phi$ decays is presented where the $J/\psi$ meson is reconstructed through its decay to an $e^+e^-$ pair. The analysis uses a sample of $pp$ collision data recorded with the LHCb experiment at centre-of-mass energies of $7$ and $8$ TeV, corresponding to an integrated luminosity of $3$ fb$^{-1}$. [...]

Search for time-dependent $CP$ violation in $D^0 \to K^+ K^-$ and $D^0 \to \pi^+ \pi^-$ decays / LHCb Collaboration
A search for time-dependent violation of the charge-parity symmetry in $D^0 \to K^+ K^-$ and $D^0 \to \pi^+ \pi^-$ decays is performed at the LHCb experiment using proton-proton collision data recorded from 2015 to 2018 at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 6 fb$^{-1}$. The $D^0$ meson is required to originate from a $D^*(2010)^+ \to D^0 \pi^+$ decay, such that its flavour at production is identified by the charge of the accompanying pion. [...]

Measurement of $CP$ asymmetry in $D^0 \to K^0_S K^0_S$ decays / LHCb Collaboration
A measurement of the $CP$ asymmetry in $D^0 \to K^0_S K^0_S$ decays is reported, based on a data sample of proton-proton collisions collected by the LHCb experiment from 2015 to 2018, corresponding to an integrated luminosity of 6 fb$^{-1}$. The flavor of the $D^0$ candidate is determined using the charge of the $D^{*\pm}$ meson, from which the decay is required to originate. [...]

Measurement of prompt-production cross-section ratio $\sigma(\chi_{c2})/\sigma(\chi_{c1})$ in $p$Pb collisions at $\sqrt{s_{NN}}$ = 8.16 TeV / LHCb Collaboration
This Letter reports the first measurement of prompt $\chi_{c1}$ and $\chi_{c2}$ charmonium production in nuclear collisions at LHC energies. The cross-section ratio $\sigma(\chi_{c2}) / \sigma(\chi_{c1})$ is measured in $p$Pb collisions at $\sqrt{s_{NN}}$~=~8.16~TeV, collected with the LHCb experiment. [...]

Precise measurement of the $f_s/f_d$ ratio of fragmentation fractions and of $B^0_s$ decay branching fractions / LHCb Collaboration
The ratio of the $B^0_s$ and $B^0$ fragmentation fractions, $f_s/f_d$, in proton-proton collisions at the LHC, is obtained as a function of $B$-meson transverse momentum and collision centre-of-mass energy from the combined analysis of different $B$-decay channels measured by the LHCb experiment. The results are described by a linear function of the meson transverse momentum, or with a function inspired by Tsallis statistics. [...]

Spectroscopy in Beauty Decays at the LHCb Experiment / LHCb Collaboration
The beauty hadron decays is unique laboratory to study charmonium and charmonium-like states, such as the $\chi_{c1}(3872)$ meson, other exotic states and the tensor $D$-wave $\Psi_2(3823)$ states. However the nature of many exotic charmonium-like candidates are still unknown. [...]

Observation of new resonances decaying to $J/ \psi K^{+}$and $J \psi\phi$ / LHCb Collaboration
The first observation of exotic states with a new quark content ccus decaying to the $J/\psi K^{+}$ final state is reported with high significance from an amplitude analysis of the $B^{+} \to J/\psi \phi K^{+} $ decay. The analysis is carried out using proton-proton collision data corresponding to a total integrated luminosity of $9{\rm{fb}^{-1}}$ collected by the LHCb experiment at centre-of-mass energies of 7, 8 and $\rm{TeV}$ .

Angular Analysis of the $B^{+}\rightarrow K^{\ast+}\mu^{+}\mu^{-}$ Decay / LHCb Collaboration
We present an angular analysis of the $B^{+}\rightarrow K^{\ast+}(\rightarrow K_{S}^{0}\pi^{+})\mu^{+}\mu^{-}$ decay using 9$\,\mbox{fb}^{-1}$ of $pp$ collision data collected with the LHCb experiment. For the first time, the full set of CP-averaged angular observables is measured in intervals of the dimuon invariant mass squared. [...]
