Coherent pion production in neutrino and antineutrino interactions on nuclei of heavy freon molecules

Measurement of Coherent π+ Production in Low Energy Neutrino-Carbon Scattering

“…The charged current coherent production cross section has been measured at neutrino energies above 7 GeV by several experiments [14][15][16][17][18] and has been found to agree with the standard coherent model developed by Rein and Sehgal. More recent model dependent searches by K2K [19] and SciBooNE [20] at neutrino energies of 0.5-2 GeV suffer from low statistics and reported null results.…”

Search for Coherent Charged Pion Production in Neutrino-Carbon Interactions

“…ÿ A, is a process in which the neutrino scatters coherently off the entire nucleus with a small energy transfer. Such a process has been measured in a number of experiments [1][2][3][4], providing a test of the partially conserved axial-vector current (PCAC) hypothesis [5]. The existing data agree with the Rein and Sehgal model [6] based on the PCAC hypothesis for neutrino energies from 7 to 100 GeV, while there exists no measurement at lower energies.…”

“…The scintillator also acts as the neutrino interaction target; it is a fully active detector and has high efficiency for low momentum particles. Scintillator strips with dimensions of 1:3 2:5 300 cm 3 are arranged in 64 layers. Each layer consists of two planes to measure horizontal and vertical position.…”

Measurement of total and differential cross sections of neutrino and antineutrino coherent π± production on carbon

“…Many measurements of NC [16][17][18][19][20][21][22][23][24] and CC [19,[25][26][27][28][29][30][31][32][33]] coherent pion production have been made at neutrino energies of 1 ≲ E ν ≲ 100 GeV using both ν μ andν μ beams and a variety of scattering target materials (carbon, neon, aluminum, argon, Freon, glass, marble, and iron). Measurements made before the discovery of neutrino oscillations were mostly made at E ν > 10 GeV.…”
