The reaction π − p → φφ n has been isolated at 16 GeV/ c and its cross section determined to be 40 ± 10 nb. The φφ mass spectrum shows a threshold enhancement between 2.1 and 2.5 GeV. A successful ...

The two-step cascade method previously used in neutron capture experiments is now applied to a proton capture reaction. The spectrum of two-step cascades populating the first 2+ level of 60Ni has been ...

We consider the three-dimensional Dirac equation in spherical coordinates with coupling to static electromagnetic potential. The space components of the potential have angular (non-central) dependence ...

An alternative calculation technique in the generator-coordinate method (GCM) has been proposed in which square-well potential between nucleon-pairs is employed, instead of the harmonic oscillator ...

We use the methods of the CALKUL Collaboration to calculate the differential cross section for e+e−→μ+μ−+2γ near the Z0 resonance. An explicit complete formula for the cross section is obtained. The ...

Four-point correlation functions are calculated for the basic operators in 2D conformal invariant theories with the central charge of the corresponding Virasoro algebra C ≤1. Based on these results, ...

APCTP Winter school on Fundamental Physics is intended to provide graduate students from member countries with an opportunity to learn some of basic subjects in fundamental physics. The main topics ...

Formulae for the line-of-sight and transverse comoving distances, proper motion distance, angular diameter distance, luminosity distance, k-correction, distance modulus, comoving volume, lookback time ...

The electric dipole moment of the Λ hyperon has been measured to be dΛ=(−3.0±7.4)×10−17e cm.

We study N=∞ lattice gauge theory at finite temperature by Monte Carlo methods using an asymmetric coupling version of the twisted Equchi-Kawai model. The data favor a first-order deconfining ...

Partial wave dispersion relations in a new formulation and fixed-s dispersion relations are used to calculate the long range contributions to the real parts of πN amplitudes. Recent results from a ...
