Recent Results from Protvino Polarized Experiment Proza-M

Single Spin Asymmetry $A_N$ (SSA) was measured at the Protvino 70 GeV accelerator. Asymmetry in the reaction $\ppdup$ is close to zero within error bars at small $|\xf|$ and $p_T<1.5$ GeV/c. SSA in the reaction $\pimp$ at polarized target fragmentation region equals to $(-13.8 \pm 3.8)%$ at $|x_f|>0.4$. There is an indication that the asymmetry begins to rise up at the same centre of mass system pion energy.

Precision Measurement of Energy and Position Resolutions of the BTeV Electromagnetic Calorimeter Prototype

The energy dependence of the energy and position resolutions of the electromagnetic calorimeter prototype made of lead tungstate crystals produced in Bogoroditsk (Russia) and Shanghai (China) is presented. These measurementswere carried out at the Protvino accelerator using a 1 to 45 GeV electron beam. The crystals were coupled to photomultiplier tubes. The dependence of energy and position resolutions on different factors as well as the measured electromagnetic shower lateral profile are presented.

Insufficiency of Available Data on the Behaviour of the Meanlives of Unstable Hadrons with Energy

We review the available evidence according to which physical media alter the Minkowskian spacetime with consequential alteration of the speed of light; we point out the apparent emergence of superluminal speeds within the hyperdense hadrons; and we point out the lack of conclusive character of the available related measure, those on the behaviour of the meanlives of unstable kaons with energy.
