p̄p low energy parameters from annihilation cross section data
Abstract. The recent experimental data obtained by the OBELIX group on total p̄p annihilation cross section are analysed; the low energy spin averaged parameters of the p̄p scattering amplitude (the imaginary parts of the S-wave scattering length and P-wave scattering volume) are extracted from the data. Their values are found to be equal to Imasc = −0.69±0.01(stat)±0.03(sys) fm, ImAsc = −0.76±0....
متن کاملLow Energy Measurement of the 18F(p,α)15O Cross Section at TRIUMF
An experiment to measure the 18F(p,α)15O cross section at low centre of mass energies has been performed with the TRIUMF-UK Detector Array (TUDA) facility at TRIUMF. Measurements of the 18F(p,α)15O reaction rate at four separate centre of mass energies; 665 keV, 430 keV, 330 keV and 250 keV, were carried out. The main goal of the experiment was the measurement of the 18F(p,α)15O cross section b...
متن کاملUpper bound on the dark matter total annihilation cross section.
We consider dark matter annihilation into standard model particles and show that the least detectable final states, namely, neutrinos, define an upper bound on the total cross section. Calculating the cosmic diffuse neutrino signal, and comparing it to the measured terrestrial atmospheric neutrino background, we derive a strong and general bound. This can be evaded if the annihilation products ...

متن کاملHigh Energy Bounds from Low Energy Data
A method for deriving rigorous upper bounds on asymptotic values of total cross sections is discussed. The size of the bound is determined by low energy data. A functional form for the total cross section at high energies is assumed and bounds on the parameters introduced are obtained. The method is applied to 7r 7~ scattering, and numerical estimates, using experimental data, are given for dif...
