چکیده
PROZA-M experiment results as well the proposal of a new spin program with the use of a polarized proton beam are presented. Significant asymmetries were observed in inclusive π production. The new program proposes to study a wealth of singleand double-spin observables in various reactions using longitudinally and transversely polarized proton beams at U70. The main goal is to define gluon contribution to nucleon spin by measuring double-spin asymmetry in charmonium production.

Single Spin Asymmetries (SSA) AN measured in the two reactions at the Protvino 70 GeV accelerator are presented. AN in the reaction p + p↑ → π 0 + X in the central region is close to zero within the error bars. SSA in the reaction π + p↑ → π 0 + X in the polarized target fragmentation region is equal to (−15 ± 4)% at |xF | > 0.4. There is an indication that the asymmetry arises at the same pion...

We study QCD in 1 + 1 dimensions in the large Nc limit using light-front Hamiltonian perturbation theory in the 1/Nc expansion. We use this formalism to exactly compute hadronic transition matrix elements for arbitrary currents at leading order in 1/Nc, which we use to write the semileptonic differential decay rate of a heavy meson and its moments. We then compare with the results obtained usin...
