Observation of focusing of 400 GeV/c proton beam with the help of bent crystals
Abstract The results of observation and studies of focusing of 400 GeV/c proton beam with the help of bent single crystals are presented. Two silicon crystals have been used in the measurements. The focal length of the first and second crystals is...

On the AdS/CFT correspondence and logarithmic operators
Abstract Logarithmic conformal field theory is investigated using the ADS/CFT correspondence and a novel method based on nilpotent weights. Using this device we add ghost fermions and point to a BRST invariance of the theory. ...

Chargino contributions to ε and ε′
Abstract We analyze the chargino contributions to the K–K̄ mixing and ε′ in the mass insertion approximation and derive the corresponding bounds on the mass insertion parameters. We find that the chargino contributions can significantly enlarge the...

Ultraviolet properties of noncommutative nonlinear σ-models in two dimensions
Abstract We discuss the ultra-violet properties of bosonic and supersymmetric noncommutative nonlinear σ-models in two dimensions, both with and without a Wess–Zumino–Witten term.

Low-energy graceful exit in anisotropic string cosmology backgrounds
Abstract We discuss the possibility of a smooth transition from the pre- to the post-big bang regime, in the context of the lowest-order string effective action (without higher-derivative corrections), taking into account with a phenomenological...

Newton potential in de Sitter braneworld
Abstract Using graviton correlator on de Sitter (dS) brane in 5d AdS or dS bulk we calculate the four-dimensional Newton potential. For flat brane in AdS bulk the Randall–Sundrum result is recovered. For flat brane in dS bulk the sign of sub-leading ...

The elastic scattering of 6Li+28Si at near-barrier energies
Abstract The 6Li+28Si elastic scattering was studied at near-barrier energies with the aim to probe the threshold anomaly. Angular distributions were measured over a wide angular range (θ lab=25° to 150°) at 4 energies, namely,...

On the super-conformal quantum mechanics in the nonlinear realizations approach
Abstract In the framework of nonlinear realizations we rederive the action of the N=2 super-conformal quantum mechanics (SCQM). We propose also the WZNW-like construction of interaction term in the Lagrangian with the help of Cartan's Omega-forms. ...

Isospin mixing in the N=Z nucleus 64Ge
Abstract The N=Z nucleus 64Ge has been investigated in two experiments using the EUROBALL III and EUROBALL IV spectrometers coupled to ancillary devices. Multipole mixing ratios, linear polarization and picosecond lifetimes for various transitions...

Two new sum rules for octet-baryon magnetic moments (μ) and constraints on QCD sum rules from new experimental determination of μ-s for the decuplet
Abstract Recently the μ Δ++ was found from a fit to π + p scattering [G.L. Castro, A. Mariano, Phys. Lett. B 517 (2002) 339]. This enable us to pinpoint condensate...

Negative-parity baryon masses using an O(a)-improved fermion action
Abstract We present a calculation of the mass of the lowest-lying negative-parity J=1/2− state in quenched QCD. Results are obtained using a non-perturbatively O(a)-improved clover fermion action, and a splitting is found...

Neutrinos that violate CPT, and the experiments that love them
Abstract Recently we proposed a framework for explaining the observed evidence for neutrino oscillations without enlarging the neutrino sector, by introducing CPT-violating Dirac masses for the neutrinos. In this Letter we continue the exploration...

CP violation, sneutrino oscillation and neutrino masses in R-parity violating supersymmetric standard model
Abstract In supersymmetric theories, sneutrino–antisneutrino mixing can occur with the oscillation time ∼0.01 ps corresponding the atmospheric neutrino mass scale ∼0.05 eV. We explore the possibility of observing sneutrino oscillation phenomena and...
