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...

Lees J, Poireau V, Tisserand V, Grauges E, Palano A, Eigen G, et al.
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  ...

Lees J, Poireau V, Tisserand V, Grauges E, Palano A, Eigen G, et al.
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...

Lees J, Poireau V, Tisserand V, Grauges E, Palano A, Eigen G, et al.
Phys Rev Lett . 2020 May; 124(15):152001. PMID: 32357020
A study of the two-body decays B^{±}→X_{cc[over ¯]}K^{±}, where X_{cc[over ¯]} refers to one charmonium state, is reported by the BABAR Collaboration using a data sample of 424  fb^{-1}. The...

Phys Rev Lett . 2020 Mar; 124(7):071802. PMID: 32142319
We present a search for nine lepton-number-violating and three lepton-flavor-violating neutral charm decays of the type D^{0}→h^{'-}h^{-}ℓ^{'+}ℓ^{+} and D^{0}→h^{'-}h^{+}ℓ^{'±}ℓ^{∓}, where h and h^{'} represent a K or π meson and...

Phys Rev Lett . 2019 Sep; 123(9):091801. PMID: 31524470
An angular analysis of the decay B[over ¯]→D^{*}ℓ^{-}ν[over ¯]_{ℓ}, ℓ∈{e,μ}, is reported using the full e^{+}e^{-} collision data set collected by the BABAR experiment at the ϒ(4S) resonance. One B...

Phys Rev Lett . 2019 Apr; 122(8):081802. PMID: 30932586
We report the observation of the rare charm decay D^{0}→K^{-}π^{+}e^{+}e^{-}, based on 468  fb^{-1} of e^{+}e^{-} annihilation data collected at or close to the center-of-mass energy of the ϒ(4S) resonance...
