Measurement of Spin-Density Matrix Elements in Photoproduction with a Linearly Polarized Photon Beam at GeV

GlueX Collaboration

We measure the spin-density matrix elements (SDMEs) for the photoproduction of off of the proton in its decay to , using 105 pb of data collected with…

High efficiency veto hadron calorimeter in the NA64 experiment at CERN

Yu. M. Andreev, A. Antonov, M. A. Ayala Torres +53

NA64 is a fixed-target experiment at the CERN SPS designed to search for Light particle Dark Matter (LDM) candidates with masses in the sub-GeV range. During the 2016-2022 runs, th…

Multiplicities of positive and negative pions, kaons and unidentified hadrons from deep-inelastic scattering of muons off a liquid hydrogen target

G. D. Alexeev, M. G. Alexeev, C. Alice +166

The multiplicities of positive and negative pions, kaons and unidentified hadrons produced in deep-inelastic scattering are measured in bins of the Bjorken scaling variable , th…

Shedding light on Dark Sectors with high-energy muons at the NA64 experiment at the CERN SPS

Yu. M. Andreev, D. Banerjee, B. Banto Oberhauser +54

A search for Dark Sectors is performed using the unique M2 beam line at the CERN Super Proton Synchrotron. New particles () could be produced in the bremsstrahlung-like reaction…

Collins and Sivers transverse-spin asymmetries in inclusive muoproduction of mesons

G. D. Alexeev, M. G. Alexeev, C. Alice +188

The production of vector mesons in deep inelastic scattering is an interesting yet scarsely explored channel to study the transverse spin structure of the nucleon and the related p…

Search for Axionlike and Scalar Particles with the NA64 Experiment

D. Banerjee, J. Bernhard, V. E. Burtsev +52

We carried out a model-independent search for light scalar (s) and pseudoscalar axionlike (a) particles that couple to two photons by using the high-energy CERN SPS H4 electron bea…
