Longitudinal double-spin asymmetry $A_{1}^{p}$ and spin-dependent structure function $g_{1}^{p}$ of the proton at small values of $x$ and $Q^{2}$

M. Aghasyan, R. Akhunzyanov, M. G. Alexeev +225

We present a precise measurement of the proton longitudinal double-spin asymmetry $A_{1}^{p}$ and the proton spin-dependent structure function $g_{1}^{p}$ at photon virtualitie…

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…

New analysis of $η π$ tensor resonances measured at the COMPASS experiment

A. Jackura, C. Fernandez-Ramirez, M. Mikhasenko +232

We present a new amplitude analysis of the $η π$ $D$ -wave in $π^{-} p \to η π^{-} p$ measured by COMPASS. Employing an analytical model based on the principles of the relativistic $S$ -mat…

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…

Omnidirectional Transport in Fully Reconfigurable Two Dimensional Optical Ratchets

Alejandro V. Arzola, Mario Villasante-Barahona, Karen Volke-Sepúlveda +2

A fully reconfigurable two-dimensional (2D) rocking ratchet system created with holographic optical micromanipulation is presented. We can generate optical potentials with the geom…

Nonclassical light from large ensemble of trapped ions

Petr Obšil, Lukáš Lachman, Tuan Pham +7

The vast majority of physical objects we are dealing with are almost exclusively made of atoms. Due to their discrete level structure, single atoms have proved to be emitters of li…

First measurement of transverse-spin-dependent azimuthal asymmetries in the Drell-Yan process

Aghasyan, R. Akhunzyanov, M. G. Alexeev +216

The first measurement of transverse-spin-dependent azimuthal asymmetries in the pion-induced Drell-Yan (DY) process is reported. We use the CERN SPS 190 GeV/ $c$ , $π^{-}$ beam and a…

First measurement of the Sivers asymmetry for gluons from SIDIS data

C. Adolph, M. Aghasyan, R. Akhunzyanov +223

The Sivers function describes the correlation between the transverse spin of a nucleon and the transverse motion of its partons. It was extracted from measurements of the azimuthal…
