First Observation of an Exotic Reggeon

G. D. Alexeev, M. G. Alexeev, C. Alice +180

We present new \compass high-statistics measurements of the peripheral production of $η π^{-}$ and $η^{'} π^{-}$ pairs in the reactions $π^{-} p \to η^{(')} π^{-} p$ . For the first t…

Search for the Decay $B_{s}^{0} \to η^{'} η$

Belle Collaboration, N. K. Nisar, V. Savinov +197

We report the results of the first search for the decay $B_{s}^{0} \to η^{'} η$ using $121.4 fb^{- 1}$ of data collected at the $Υ (5 S)$ resonance with the Belle dete…

Spin Density Matrix Elements in Exclusive $ω$ Meson Muoproduction $^{*}$

M. G. Alexeev, G. D. Alexeev, A. Amoroso +197

We report on a measurement of Spin Density Matrix Elements (SDMEs) in hard exclusive $ω$ meson muoproduction on the proton at COMPASS using 160 GeV/ $c$ polarised $μ^{+}$ and $ μ^{…

Measurement of two-particle correlations in hadronic $e^{+} e^{-}$ collisions at Belle

Belle Collaboration, A. Abdesselam, I. Adachi +459

The enhancement of charged-particle pairs with large pseudorapidity difference and small azimuthal angle difference, often referred to as the ``ridge signal'', is a phenomenon wide…

Contribution of exclusive diffractive processes to the measured azimuthal asymmetries in SIDIS

J. Agarwala, M. G. Alexeev, G. D. Alexeev +203

Hadron leptoproduction in Semi-Inclusive measurements of Deep-Inelastic Scattering (SIDIS) on unpolarised nucleons allows one to get information on the intrinsic transverse momentu…

Measurement of $R (D)$ and $R (D^{*})$ with a semileptonic tagging method

The Belle Collaboration, G. Caria, P. Urquijo +188

The experimental results on the ratios of branching fractions $R (D) = B (B ˉ \to D τ^{-} ν ˉ_{τ}) / B (B ˉ \to D ℓ^{-} ν ˉ_{ℓ})$ and $\mathcal{R}(D^…
