Transverse momentum dependent nucleon structure from pions impinged on a transversely polarized proton target
… ability to measure the products from a polarized target and also because the beam can be modified to measure the SIDIS and Drell-Yan processes. The COMPASS collaboration collected transverse spin-dependent data to measure the Sivers function from SIDIS and in 2016 COMPASS published the results of …

A search for vμ --> ve oscillations
… Vmu -+ Ve The detector is 1 kilometer from the proton target and was exposed to a narrow band beam with peak energies of 1.25 and 1.45GeV. We observe 54 electron events with a background of 31.6 ± 5.6 ± 4.4. The observed excess of electron events is consistent with oscillations at the level 1.8 …

A search for Muon-Associated Neutrino--->electron-Associated neutrino oscillations
… \nu\sb{e}$. The detector is 1 kilometer from the proton target and was exposed to a narrow band beam with peak energies of 1.25 and 1.45 GeV. We observe 54 electron events with a background of 31.6 $\pm$ 5.6 $\pm$ 4.4. The observed excess of electron events is consistent with oscillations at the …

Dynamic proton polarization in some rare earth ethyl sulphates
"Measurements of the dynamic polarization of protons by the solid state effect (""ef£et solide"") have been made at liquid helium temperatures on single crystals of erbium-doped and neodymium-doped yttrium ethyl sulphate ( (Er, Y)ES and (Nd, Y)ES). T he dynamic polarization was induced by …

Measurement of spin parameters A and Ann in np and pp elastic scattering at 6 G3V/c
… 12 GeV/c polarized deuteron beam and a polarized proton target at the Argonne ZGS. The recoil proton was measured by a conventional magnetic spectrometer, while the scattered neiitron/proton was detected in a brass-scintillator neutron converter/detector. Clean elastic signals were seen in both …

Measurement of the Deeply Virtual Neutral Pion Electroproduction Cross Section off the Proton at 10.6 GeV using the CLAS12 Detector
… using 10.6 GeV electron scattering data off a proton target from the CLAS12 experiment in Jefferson Lab Hall B. This measurement is important as exclusive meson production has unique access to the chiral odd Generalized Parton Distributions, and is also a background for other exclusive …

Measurement of the D*+- cross-section at HERMES
… the electroproduction of D^{*+/-} mesons on a proton target has been measured in a fixed target experiment with a lepton beam energy of 27.5 GeV. The analysis is based on data collected by HERMES in 1997. From this result, the open charm photoproduction cross-section is determined for a photon …

Transverse Spin Structure of the Proton Studied in Semi–inclusive DIS
… been taking data with a transversely polarised proton target since 2002. This PhD work covers the analysis of the HERMES data recorded in the years 2002 through 2004 including extensive systematic studies. In addition, several Monte Carlo generators have been used for the estimation of …
