Investigation on steering of ultrarelativistic beam through an axially oriented bent crystal
L. Bandiera, I. V. Kyryllin, C. Brizzolari +12
An investigation on stochastic deflection of high-energy charged particles in a bent crystal was carried out. In particular, we investigated the deflection efficiency under axial c…
Photoproduction of the meson using the CLAS detector
M. ~Carver, A. ~Celentano, K. ~Hicks +137
The quark structure of the meson has, for many years, been assumed to be a pure quark-antiquark () resonance with quantum numbers . Recently,…
Beam spin asymmetry in semi-inclusive electroproduction of a hadron pair
M. Mirazita, H. Avakian, A. Courtoy +140
A first measurement of the longitudinal beam spin asymmetry ALU in the semi-inclusive electroproduction of pairs of charged pions is reported. ALU is a higher-twist observable and…
Progress towards the first measurement of charm baryon dipole moments
S. Aiola, L. Bandiera, G. Cavoto +18
Electromagnetic dipole moments of short-lived particles are sensitive to physics within and beyond the Standard Model of particle physics but have not been accessible experimentall…
Measurement of the Principal Quantum Number Distribution in a Beam of Antihydrogen Atoms
B. Kolbinger, C. Amsler, S. Arguedas Cuendis +35
The ASACUSA (Atomic Spectroscopy And Collisions Using Slow Antiprotons) collaboration plans to measure the ground-state hyperfine splitting of antihydrogen in a beam at the CERN An…
Extraction of beam-spin asymmetries from the hard exclusive channel off protons in a wide range of kinematics
S. Diehl, K. Joo, A. Kim +135
We have measured beam-spin asymmetries to extract the moment from the hard exclusive reaction above the resonance region, fo…
An experimental program with high duty-cycle polarized and unpolarized positron beams at Jefferson Lab
A. Accardi, A. Afanasev, I. Albayrak +227
Positron beams, both polarized and unpolarized, are identified as essential ingredients for the experimental programs at the next generation of lepton accelerators. In the context…
The ENUBET positron tagger prototype: construction and testbeam performance
F. Acerbi, M. Bonesini, F. Bramati +50
A prototype for the instrumented decay tunnel of ENUBET was tested in 2018 at the CERN East Area facility with charged particles up to 5 GeV. This detector is a longitudinal sampli…
Investigation on radiation generated by Sub-GeV electrons in ultrashort Si and Ge bent crystals
L. Bandiera, A. Sytov, D. De Salvador +16
We report on the measurements of the spectra of gamma radiation generated by 855 MeV electrons in bent silicon and germanium crystals at MAMI (MAinzer MIkrotron). The crystals were…
Decay tunnel instrumentation for the ENUBET neutrino beam
F. Acerbi, A. Berra, M. Bonesini +56
The uncertainty in the initial neutrino flux is the main limitation for a precise determination of the absolute neutrino cross section. The ERC funded ENUBET project (2016-2021) is…
Probing the core of the strong nuclear interaction
A. Schmidt, J. R. Pybus, R. Weiss +162
The strong nuclear interaction between nucleons (protons and neutrons) is the effective force that holds the atomic nucleus together. This force stems from fundamental interactions…
First measurement of direct photoproduction of the meson on the proton
A. Celentano, M. Battaglieri, R. De Vita +4
We present the first measurement of the exclusive reaction in the photon energy range - GeV and four-momentum transfer squared $0.2<-t<2…
The hadronic beamline of the ENUBET neutrino beam
ENUBET collaboration, C. Delogu, F. Acerbi +57
The ENUBET ERC project (2016-2021) is studying a facility based on a narrow band beam capable of constraining the neutrino fluxes normalization through the monitoring of the associ…
Polysiloxane-based scintillators for shashlik calorimeters
F. Acerbi, A. Branca, C. Brizzolari +46
We present the first application of polysiloxane-based scintillators as active medium in a shashlik sampling calorimeter. These results were obtained from a testbeam campaign of a…
