Observation of $\Xi^0_b \to \Xi^0 J/\psi$ and evidence for $\Xi^0_b \to \Xi^0 \psi(2S)$ decays

Roel Aaij, Mohammed Abdelfatah, Ahmed Sameh Wagih Abdelmotteleb, Carlos Abellan Beteta et autres

The first search for the beauty baryon decays $\Xi_{b}^{0} \to \Xi^{0} J/\psi$ and $\Xi_{b}^{0} \to \Xi^{0} \psi(2S)$ is presented using the proton-proton collision dataset collected by the LHCb experiment between 2016 and 2018, corresponding to an integrated luminosity of $5.4\,\mathrm{fb}^{-1}$. The first …

Observation of the $\Xi_ c^0\to pK^-$ decay and measurement of its asymmetry parameter

Roel Aaij, Mohammed Abdelfatah, Ahmed Sameh Wagih Abdelmotteleb, Carlos Abellan Beteta et autres

A search for the Cabibbo-suppressed decay $\Xi_c^0 \to p K^-$ is performed using $pp$ collision data corresponding to an integrated luminosity of $5.4\,\mathrm{fb}^{-1}$, collected by the LHCb experiment at a centre-of-mass energy of $13\,\mathrm{TeV}$. The decay is observed for the first time …

Observation of several sources of $C\!P$ violation in $B^+ \!\to K^+ \pi^+ \pi^-$ decays

Roel Aaij, Mohammed Abdelfatah, Ahmed Sameh Wagih Abdelmotteleb, Carlos Abellan Beteta et autres

An amplitude analysis of $B^+ \!\to K^+ \pi^+ \pi^-$ decays is presented in which six $C\!P$-violating phenomena are judged to be of significance for the first time. This analysis is based on $pp$ collision data recorded with the LHCb detector in 2011--2012, …

Resolution of outstanding puzzles in $B^+ \!\to K^+ \pi^+ \pi^-$ decays

Roel Aaij, Mohammed Abdelfatah, Ahmed Sameh Wagih Abdelmotteleb, Carlos Abellan Beteta et autres

An amplitude analysis of $B^+ \!\to K^+ \pi^+ \pi^-$ decays is presented, based on $pp$ collision data recorded with the LHCb detector in 2011--2012, corresponding to an integrated luminosity of $3\,\text{fb}^{-1}$. Previous studies of the $B \!\to K \pi \pi$ sector have …

Amplitude analysis of $B^+ \!\to K^+ \pi^+ \pi^-$ decays

Roel Aaij, Mohammed Abdelfatah, Ahmed Sameh Wagih Abdelmotteleb, Carlos Abellan Beteta et autres

The branching fractions and quasi-two-body $C\!P$-violating asymmetries of intermediate states obtained through an amplitude analysis of the charmless three-body decay $B^+ \!\to K^+ \pi^+ \pi^-$ are reported. The analysis is based on $pp$ collision data at centre-of-mass energies $\sqrt{s}=7$ and $8\,\text{TeV}$ recorded …

Evidence for the decay $B_s^0\to \phi \eta^\prime$

Roel Aaij, Mohammed Abdelfatah, Ahmed Sameh Wagih Abdelmotteleb, Carlos Abellan Beteta et autres

Using a dataset corresponding to an integrated luminosity of $9 \,\textrm{fb}^{-1}$ collected in proton-proton collisions between 2011 and 2018 by the LHCb experiment, evidence is found for the decay $B^0_s\rightarrow\phi\eta'$ with $3.5 \sigma$ significance. The branching ratio relative to the $B^0_s\rightarrow\phi\phi$ decay …

First evidence of the decay $B^+ \to \pi^+ e^+ e^-$

Roel Aaij, Ahmed Sameh Wagih Abdelmotteleb, Carlos Abellan Beteta, Fernando Jesus Abudinén et autres

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$^{-1}$. A signal excess with a …

Observation of the doubly charmed baryon $\it{\Xi}_{cc}^+$ with the LHCb Run 3 detector

Roel Aaij, Mohammed Abdelfatah, Ahmed Sameh Wagih Abdelmotteleb, Carlos Abellan Beteta et autres

The first observation of the doubly charmed baryon $\it{\Xi}_{cc}^+$ is reported through its decay to the $\it{\Lambda}_c^+ K^-\pi^+$ final state, with a statistical significance exceeding seven standard deviations. The observation is made using proton-proton collision data collected in 2024 with the LHCb …
