= 4.918 and 4.951 GeV with the BESIII detector, we report the first observation of Λ c (2595)+ and Λ c ...

A measurement of the Higgs boson mass and width via its decay to two Z bosons is presented. Proton-proton collision data collected by the CMS experiment, corresponding to an integrated luminosity of 138 fb(-1) at a center-of-mass energy of 13 TeV, is used. ...

A search for beyond the standard model spin-0 bosons, phi, that decay into pairs of electrons, muons, or tau leptons is presented. The search targets the associated production of such bosons with a W or Z gauge boson, or a top quark-antiquark pair, and use ...

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. Readout of all detectors into an al ...

The interpretation of cosmic antiproton flux mea- surements from space-borne experiments is currently limited by the knowledge of the antiproton production cross-section in collisions between primary cosmic rays and the interstel- lar medium. Using collisi ...

Two new excited states, S2c(3185)0 and S2c(3327)0, are observed in the E thorn c K- invariant-mass spectrum using proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb-1. Five previously observed e ...

EOS is an open-source software for a variety of computational tasks in flavor physics. Its use cases include theory predictions within and beyond the Standard Model of particle physics, Bayesian inference of theory parameters from experimental and theoreti ...

We report the first direct measurement of the inclusive branching fraction B(B-s -> DsX) via B-s tagging in e(+)e(-) -> gamma(5S) events. Tagging is accomplished through a partial reconstruction of semileptonic decays B-s -> D(s)Xl nu, where X denotes unre ...

A new baryon state is observed in the Lambda(0)(b)pi(+)pi(-) mass spectrum with high significance using a data sample of pp collisions, collected with the LHCb detector at centre-of-mass energies root s = 7, 8 and 13 TeV, corresponding to an integrated lum ...
