Structure near $K^-$+$p$+$p$ threshold in the in-flight $^3$He$(K^-,\Lambda p)n$ reaction

, 2016
To search for an S= -1 di-baryonic state which decays to $\Lambda p$, the $ {\rm{}^3He}(K^-,\Lambda p)n_{missing}$ reaction was studied at 1.0 GeV/$c$. Unobserved neutrons were kinematically identified from the missing mass $M_X$ of the $ {\rm{}^3He}(K^-,

A Hopf Bifurcation in a Three-Component Reaction-Diffusion System with a Chemoattraction

Abstract and Applied Analysis, 2013
We consider a three-component reaction-diffusion system with a chemoattraction. The purpose of this work is to analyze the chemotactic effects due to the gradient of the chemotactic sensitivity and the shape of the interface.

On the Formation of CO2 and Other Interstellar Ices

, 2011
We investigate the formation and evolution of interstellar dust-grain ices under dark-cloud conditions, with a particular emphasis on CO2. We use a three-phase model (gas/surface/mantle) to simulate the coupled gas--grain chemistry, allowing the ...

Measurement of quasi-elastic 12C(p,2p) scattering at high momentum transfer

, 1997
We measured the high-momentum quasi-elastic 12C(p,2p) reaction (at center of mass angle near 90 degrees) for 6 and 7.5 GeV/c incident protons. The three-momentum components of both final state protons were measured and the missing energy and momentum of ...
