Photoproduction of neutral pions in helium by 335 MEV Bremsstrahlung
… was measured for the, coherent production of neutral pions from He4 by photons to an energy of 335 MeV. Bremsstrahlung from the University of Illinois 340 MeV betatron impinged upon a gaseous He4 target cooled to 20.4oK. The recoil nucleus was detected with a semiconductor telescope in …

Analysis of the neutral D-meson decay to a neutral kaon and two neutral pions
This thesis presents a Dalitz plot analysis of D0 to K0S PI0 PI0 using the CLEO-c data set of 818 inverse picobarns of positron-electron collisions accumulated at center-of-mass energy 3.77 GeV. This corresponds to about 3 million D0-anti-D0 pairs from which we select 1260 tagged candidates with a …

A Search for CP Violation in and a Dalitz Analysis of Neutral D Mesons Decaying to Pions, Antipions, and Neutral Pions in CLEO II.V
Using the 9fb-1 data sample collected with the CLEO II.V detector at the Cornell Electron Storage Ring, we study the resonant substructure of the Cabibbo suppressed decay D 0 → pi+pi-pi 0. We observe significant contributions from the rho- pi+, rho+pi-, rho 0pi0, and non-resonant channels, and …

Neutral Pion Double Helicity Asymmetry in Polarized Proton-Proton Collisions at [the square root of sigma]=200 GeV at STAR
… asymmetry, ALL, of various final-state channels. Neutral pions provide a potentially powerful final state because they are copiously produced in p+p collisions and have few backgrounds. In 2009, STAR took 14 pb-¹ of integrated luminosity of 200 GeV p+p collisions, with average beam longitudinal …

Untersuchung neutraler pi-Mesonen mit dem elektromagnetischen Kalorimeter des BABAR-Detektors
… a momentum spectrum of inclusively produced neutral pions (Y(4S) -> pi0 X and e+e- -> q anti-q -> pi0 X, respectively) was determined. For continuum events also a momentum depending angle distribution was determined. From these distributions the average number of produced pi0 per …

Measurement of transverse spin asymmetries in polarized proton-proton collisions, and the realization of new electromagnetic calorimeters for forward physics
… At mid-rapidity, precision asymmetries for neutral pions and η mesons are measured. These asymmetries are consistent with zero, and are expected to place bounds on the gluon Sivers function. Lastly, an exploratory double transverse spin asymmetry, AT T , measurement is carried out using …

Suppression of High Transverse Momentum Charged Hadrons in Au+Au Collisions at 200 GeV Nucleon-Nucleon Center of Mass Energy
… mechanisms in the Quark-Gluon Plasma. Presently, neutral pions provide the best measurement at RHIC of single particle suppression. Charged hadrons have independent sources of systematic uncertainty and can thus provide additional constraints. Background from off-vertex sources such as photon …
