Galactic and Extragalactic Analysis of the Astrophysical Muon Neutrino Flux with 12.3 years of IceCube Track Data / IceCube Collaboration
The Ice Cube Neutrino Observatory has been measuring an isotropic astrophysical neutrino flux in multiple detection channels for almost a decade. Galactic diffuse emission, which arises from the interactions between cosmic rays and the interstellar medium, is an expected signal in IceCube. [...]

Measurement of Ξc+ production in pPb collisions at sNN=8.16 TeV at LHCb / LHCb Collaboration
A study of prompt Ξc+ production in proton-lead collisions is performed with the LHCb experiment at a centre-of-mass energy per nucleon pair of 8.16 TeV in 2016 in pPb and Pbp collisions with an estimated integrated luminosity of approximately 12.5 and 17.4 nb1, respectively. The Ξc+ production cross-section, as well as the Ξc+ to Λc+ production cross-section ratio, are measured as a function of the transverse momentum and rapidity and compared to latest theory predictions.

Measurement of the ratios of branching fractions R(D) and R(D0) / LHCb Collaboration
The ratios of branching fractions R(D)B(B¯Dτν¯τ)/B(B¯Dμν¯μ) and R(D0)B(BD0τν¯τ)/B(BD0μν¯μ) are measured, assuming isospin symmetry, using a sample of proton-proton collision data corresponding to 3.0 fb1 of integrated luminosity recorded by the LHCb experiment during 2011 and 2012. The tau lepton is identified in the decay mode τμντν¯μ. [...]

A study of CP violation in the decays B±[K+Kπ+π]Dh± (h=K,π) and B±[π+ππ+π]Dh± / LHCb Collaboration
The first study of CP violation in the decay mode B±[K+Kπ+π]Dh±, with h=K,π, is presented, exploiting a data sample of proton-proton collisions collected by the LHCb experiment that corresponds to an integrated luminosity of 9 fb1. The analysis is performed in bins of phase space, which are optimised for sensitivity to local CP asymmetries. [...]

First observation and branching fraction measurement of the Λb0Dsp decayFirst observation and branching fraction measurement of the Λb0Dsp decay / LHCb Collaboration
The first observation of the Λb0Dsp decay is presented using proton-proton collision data collected by the LHCb experiment at a centre-of-mass energy of s=13TeV, corresponding to a total integrated luminosity of 6fb1. Using the Λb0Λc+π decay as the normalisation mode, the branching fraction of the Λb0Dsp decay is measured to be B(Λb0Dsp)=(12.6±0.5±0.3±1.2)×106, where the first uncertainty is statistical, the second systematic and the third due to uncertainties in the branching fractions of the Λb0Λc+π, DsKK+π and Λc+pKπ+ decays..

Search for the rare decays W+Ds+γ and ZD0γ at LHCb / LHCb Collaboration
A search for the rare decays W+Ds+γ and ZD0γ is performed using proton-proton collision data collected by the LHCb experiment at a centre-of-mass energy of 13 TeV, corresponding to an integrated luminosity of 2.0 fb1. No significant signal is observed for either decay mode and upper limits on their branching fractions are set using W+μ+ν and Zμ+μ decays as normalization channels. [...]

First observation of the B+Ds+DsK+ decay / LHCb Collaboration
The B+Ds+DsK+ decay is observed for the first time using proton-proton collision data collected by the LHCb detector at centre-of-mass energies of 7, 8 and 13TeV, corresponding to an integrated luminosity of 9fb1. Its branching fraction relative to that of the B+D+DK+ decay is measured to be B(B+Ds+DsK+)B(B+D+DK+)=0.525±0.033±0.027±0.034, where the first uncertainty is statistical, the second systematic, and the third is due to the uncertainties on the branching fractions of the Ds±KK±π± and D±Kπ±π± decays.
