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 …

Stringent limits on $C\!PT$- and Lorentz-invariance violation from $B_s^0$ meson decays

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

Tests of fundamental symmetries, such as $CPT$ and Lorentz invariance, provide sensitive probes of physics beyond the standard quantum-field-theory framework. Possible violations of these symmetries are investigated through interference effects in decays of $B_s^0$ mesons to $D_s^-\pi^{+}$ states. The analysis uses proton-proton …

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 …

Angular analysis of the decay ${\it \Lambda}_{\it b}^{0} \to {\it \Lambda}(1520){\it \mu^{+}\mu^{-}}$

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

The first angular analysis of ${\it \Lambda}_{\it b}^{0} \to {\it \Lambda}(1520)\mu^{+}\mu^{-}$ decays is presented, using proton-proton collision data collected with the LHCb detector between 2011 and 2018, corresponding to an integrated luminosity of 9 fb$^{-1}$. The leptonic forward-backward asymmetry, $A_\text{FB, 3/2}^\ell$, and …

Improved measurement of $C\!P$ violation in $B^{0}_{s} \!\to J/\psi\pi^{+}\pi^{-}$ decays

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

The time-dependent $C\!P$ asymmetry in $B^{0}_{s} \!\to J/\psi\pi^{+}\pi^{-}$ decays is measured using proton-proton collision data, corresponding to an integrated luminosity of $6\,\text{fb}^{-1}$, collected with the LHCb detector at a centre-of-mass energy of $13\,\text{TeV}$ during $\mbox{2015--2018}$. The $C\!P$-violating phase, $\phi_{s}$, the direct $C\!P$-violation …

Model-independent measurement of the transversity amplitudes of the $B^0\to K^{*0}\mu^+\mu^-$ decay

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

An analysis of the decay amplitudes of $B^0 \to K^{*0}(\to K^+\pi^-)\mu^+\mu^-$ is presented, 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 8.4~fb$^{-1}$. The amplitudes are constructed …

Study of muon-tagged $D_{s1}(2460)^+$ and $D_{s1}(2536)^+$ decays to the $D_s^{+}π^+π^-$ final state

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

Decays of the pseudovector $D_{s1}(2460)^+$ and $D_{s1}(2536)^+$ mesons to the three-body $D_{s}^+π^+π^-$ final state are studied. The data sample is based on decays of beauty hadrons into $D_{s1}^+$ states accompanied by a muon from the $b$-hadron decay chain collected by the LHCb …
