Transverse-momentum-dependent Multiplicities of Charged Hadrons in Muon-Deuteron Deep Inelastic Scattering

M. Aghasyan, R. Akhunzyanov, M. G. Alexeev +227

A semi-inclusive measurement of charged hadron multiplicities in deep inelastic muon scattering off an isoscalar target was performed using data collected by the COMPASS Collaborat…

Search for muoproduction of $X (3872)$ at COMPASS and indication of a new state $X (3872)$

M. Aghasyan, R. Akhunzyanov, M. G. Alexeev +224

We have searched for exclusive production of exotic charmonia in the reaction $μ^{+} N \to μ^{+} (J / ψ π^{+} π^{-}) π^{\pm} N^{'}$ using COMPASS data collected with incoming muons of…

Multiplicities of charged pions and unidentified charged hadrons from deep-inelastic scattering of muons off an isoscalar target

C. Adolph, J. Agarwala, M. Aghasyan +224

Multiplicities of charged pions and unidentified hadrons produced in deep-inelastic scattering were measured in bins of the Bjorken scaling variable $x$ , the relative virtual-photo…

Odd and Even Partial Waves of $η π^{-}$ and $η^{'} π^{-}$ in $π^{-} p \to η^{(')} π^{-} p$ at $191 GeV / c$

C. Adolph, R. Akhunzyanov, M. G. Alexeev +205

Exclusive production of $η π^{-}$ and $η^{'} π^{-}$ has been studied with a $191 GeV / c$ $π^{-}$ beam impinging on a hydrogen target at COMPASS (CERN). Partial-wave analyses reveal d…

A search for decay $η^{'} \to 4 π^{0}$ with GAMS- $4 π$ Setup

S. V. Donskov, V. N. Kolosov, A. A. Lednev +4

A search for rare decay $η^{'} \to 4 π^{0}$ has been performed with GAMS-4 $π$ Setup. The new upper limit for decay was established $BR(η' \rightarrow 4 π^{0}) < 3.2 \cdot 10^{…

Leading and Next-to-Leading Order Gluon Polarisation in the Nucleon and Longitudinal Double Spin Asymmetries from Open Charm Muoproduction

C. Adolph, M. G. Alekseev, V. Yu. Alexakhin +217

The gluon polarisation in the nucleon was measured using open charm production by scattering 160 GeV/c polarised muons off longitudinally polarised protons or deuterons. The data w…

Flavour Separation of Helicity Distributions from Deep Inelastic Muon-Deuteron Scattering

COMPASS Collaboration, M. Alekseev

We present a LO evaluation of helicity densities of valence, Δu_v+Δd_v, non-strange sea, Δ\bar{u}+Δ\bar{d}, and strange quarks, Δs (assumed to be equal to Δ\bar{s}). They have been…
