Quasielastic charmed-baryon production and exclusive strange-particle production by high-energy neutrinos

Abstract

Three charmed-baryon candidates produced in the quasielastic reaction v n + p -A : + p -A~+ were found in an exposure of the Fermilab deuterium-filled 15-ft bubble chamber to a wide-band neutrino beam. We also found that the cross section of the associated-production reaction vn -p -A K + is (5.5k 1.3k1.1 ) X lop4' cm2 for EV > 10 GeV, and is approximately independent of energy. In addition we studied the cross sections of some quasi-two-body associated strange-particle production reactions other than p p A K + .

Measurement of charged kaon production by neutrinos at MINERvA

“…With 885 (201) reconstructed K + events after subtracting backgrounds in the charged-current (neutral-current) analysis, these results represent a significant step forward over previous measurements in bubble chambers with a few 10s of events total [66,67,68,69,70]. In addition, charged-current coherent K + production by neutrinos has been observed for the first time at 3.0σ significance.…”

“…Strange particle production by neutrinos has previously been observed in bubble chambers [60,61,62,63,64,65,66,67,68,69,70] and the straw tube detector NOMAD [71]. Bubble chambers have exquisite position resolution, and are fantastic detectors for Λ and K 0 S , neutral particles which travel a few centimeters before decaying.…”

New evaluation of the axial nucleon form factor from electron- and neutrino-scattering data and impact on neutrino-nucleus cross sections

“…We fit the pion electroproduction data as reported in [25], from various sources [95][96][97][98][99], and the neutrino-scattering data as reported in [20], from various sources [12,13,17,18,100]. The pion electroproduction data can be interpreted in different theory frameworks to extract the form factor.…”
