Lees J, Poireau V, Tisserand V, Grauges E, Palano A, Eigen G, et al.
Phys Rev Lett . 2023 Dec; 131(20):201801. PMID: 38039482
A new dark sector antibaryon, denoted ψ_{D}, could be produced in decays of B mesons. This Letter presents a search for B^{+}→ψ_{D}+p (and the charge conjugate) decays in e^{+}e^{-} annihilations...

Lees J, Poireau V, Tisserand V, Grauges E, Palano A, Eigen G, et al.
Phys Rev Lett . 2022 Apr; 128(13):131802. PMID: 35426701
Axionlike particles (ALPs) are predicted in many extensions of the standard model, and their masses can naturally be well below the electroweak scale. In the presence of couplings to electroweak...

Lees J, Poireau V, Tisserand V, Grauges E, Palano A, Eigen G, et al.
Phys Rev Lett . 2022 Mar; 128(9):091804. PMID: 35302790
We report on the first search for electron-muon lepton flavor violation (LFV) in the decay of a b quark and b antiquark bound state. We look for the LFV decay...

Lees J, Poireau V, Tisserand V, Grauges E, Palano A, Eigen G, et al.
Phys Rev Lett . 2022 Jan; 128(2):021802. PMID: 35089770
Collider searches for dark sectors, new particles interacting only feebly with ordinary matter, have largely focused on identifying signatures of new mediators, leaving much of dark sector structures unexplored. In...

Phys Rev Lett . 2021 Jan; 125(24):241801. PMID: 33412062
We report on a precision measurement of the ratio R_{τμ}^{ϒ(3S)}=B(ϒ(3S)→τ^{+}τ^{-})/B(ϒ(3S)→μ^{+}μ^{-}) using data collected with the BABAR detector at the SLAC PEP-II e^{+}e^{-} collider. The measurement is based on a 28  ...

Phys Rev Lett . 2020 Dec; 125(23):231801. PMID: 33337231
A search for the decay K_{S}^{0}→μ^{+}μ^{-} is performed using proton-proton collision data, corresponding to an integrated luminosity of 5.6  fb^{-1} and collected with the LHCb experiment during 2016, 2017, and...

Phys Rev Lett . 2020 Dec; 125(21):212001. PMID: 33275017
A study of prompt charm-hadron pair production in proton-lead collisions at sqrt[s_{NN}]=8.16  TeV is performed using data corresponding to an integrated luminosity of about 30  nb^{-1}, collected with the LHCb...

Phys Rev Lett . 2020 Nov; 125(18):181801. PMID: 33196250
Many scenarios of physics beyond the standard model predict the existence of new gauge singlets, which might be substantially lighter than the weak scale. The experimental constraints on additional scalars...

Phys Rev Lett . 2020 Jul; 125(1):011802. PMID: 32678626
An angular analysis of the B^{0}→K^{*0}(→K^{+}π^{-})μ^{+}μ^{-} decay is presented using a dataset corresponding to an integrated luminosity of 4.7  fb^{-1} of pp collision data collected with the LHCb experiment. The...
