چکیده

Light antinuclei, like antideuteron and antihelium-3, are ideal probes for new, exotic physics because their astrophysical backgrounds suppressed at low energies. In order to exploit fully the inherent discovery potential of light a reliable description production cross sections in cosmic ray interactions is crucial. We provide therefore antihelium-3 $pp$, $p$He, He$p$, HeHe, $\bar pp$ p$He collisions energies relevant secondary Milky Way, tabulated form which convinient use. These predictions based on QGSJET-II-04m state art coalescence model WiFunC, evaluates coalesence probability an event-by-event basis, including both momentum correlations dependence emission volume. addition, we comment importance Monte Carlo use event generators general. particular, discuss effect two-particle provided by antinuclei production.

Explicit Temperature Treatment in Monte Carlo Neutron Tracking Routines — First Results

This article discusses the preliminary implementation of the new explicit temperature treatment method to the development version Monte Carlo reactor physics code Serpent 2 and presents the first practical results calculated using the method. The explicit temperature treatment method, as introduced in [1], is a stochastic method for taking the effect of thermal motion into account on-the-fly in...

Efficient Sequential Monte Carlo Using Interpolation

A limitation common to all sequential Monte Carlo algorithms is the computational demand of accurately describing an arbitrary distribution, which may preclude real-time implementation for some systems. We propose using interpolation to construct a high accuracy approximation to the importance density. The surrogate density can then be efficiently evaluated in place of sampling the true importa...
