Observation of electroweak production of two jets and a Z-boson pair
(Nature Research, 2023-02)
Electroweak symmetry breaking explains the origin of the masses of elementary particles through their interactions with the Higgs field. Besides the measurements of the Higgs boson properties, the study of the scattering ...
Search for B mesogenesis at B a B ar
(2023-05-01)
A new mechanism has been proposed to simultaneously explain the presence of dark matter and the matter-antimatter asymmetry in the Universe. This scenario predicts exotic B-meson decays into a baryon and a dark-sector ...
Measurement of additional radiation in the initial-state-radiation processes e+e- →μ+μ-γ and e+e- →π+π-γ at BABAR
(American Physical Society, 2023-12-21)
A dedicated measurement of additional radiation in e+e-→μ+μ-γ and e+e-→π+π-γ initial-state-radiation events is presented using the full BABAR data sample. For the first time results are presented at next-to- and ...
Precision e- beam polarimetry at an e+e- B factory using tau-pair events
(American Physical Society (APS), 2023-11-01)
Search for Evidence of Baryogenesis and Dark Matter in B^{+}→ψ_{D}+p Decays at BABAR.
(2023-11-17)
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 at 10.58 GeV, using data ...
