Infinite Dimensional Geometry and Quantum Field Theory of Strings. I. Infinite Dimensional Geometry of Second Quantized Free String
There are investigated several objects of an INFINITE DIMENSIONAL GEOMETRY
appearing from the second quantization of a free string. The paper contains 2
chapters: 1st is devoted to the infinite dimensional geometry of flag,
fundamental and -spaces for Virasoro-Bott group and its nonassociative
deformation defined by Gelfand-Fuchs 3-cocycle (Gelfand-Fuchs loop) as well as
of infinite-dimensional non-Euclidean symplectic grassmannian, to the
constructions of Verma modules, their models and skladens over Virasoro
algebra; an infinite dimensional geometry of the configuration space for the
second quantized free string in flat and curved backgrounds as well as author
version of Bowick- Rajeev formalism of the separation of internal and external
degrees of freedom of a closed string are described in 2nd chapter. In the 1st
chapter the main objects are infinite dimensional Lie algebras, groups and
loops, homogeneous, K\"ahler, Finsler, contact and symmetric spaces, complex,
real and CR-manifolds, determinant sheaves, manifolds with subsymmetries,
polarizations and Fock spaces, bibundles and objects of integral geometry,
nonholonomic spaces, deformations of geometric structures and moduli spaces. In
the 2nd chapter they are gauge fields, Faddeev-Popov ghosts, Gauss-Manin
connections, Kostant-Blattner-Sternberg pairings, BRST-operators.Comment: 20 pages. It is a version of the text published by the independent

Results of measurements of the analyzing powers for polarized neutrons on C, CH <inf>2</inf> and Cu targets for momenta between 3 and 4.2 GeV/c
The analyzing powers for neutron charge exchange nA → pX reactions on nuclei have been measured on C, CH2 and Cu targets at incident neutron momenta 3.0 - 4.2 GeV/c by detecting one charged particle in forward direction. The polarized neutron measurements are the first of their kind. The experiment was performed using the Nuclotron accelerator in JINR Dubna, where polarized neutrons and protons were obtained from breakup of a polarized deuteron beam which has a maximum momentum of 13 GeV/c. The polarimeter ALPOM2 was used to obtain the analyzing power dependence on the transverse momentum of the final-state nucleon. These data have been used to estimate the figure of merit of a proposed experiment at Jefferson Laboratory to measure the recoiling neutron polarization in the quasi-elastic 2H(e, e'n) reaction, which yields information on the charge and magnetic elastic form factors of the neutron
