This report presents my work for Double Chooz at MIT during the 2009 Summer REU program, funded by Columbia University. Double Chooz is a reactor neutrino experiment that aims to measure the mixing parameter θ13. The experiment detects electron antineutrinos via inverse beta decay. Neutrons and light nuclei made in muon spallation are a major background to the experiment. The delayed neutron em...

The present paper deals with the solid state etch-track detectors and their applications to the detection/dosimetry of neutrons, radon, and radon-decay products. Most of the scientists, actively engaged in the late 60’s and in the 70’s for monitoring the occupational neutron-exposure by etch-track detectors, became also involved in the development of personal monitors for the exposure to radon-...

We argue that the strong interaction between protons and neutrons in the asymmetric liquid (neutron star) distorts strongly proton Fermi surface. We use the Feynman diagram approach to calculate probability of triple (e-p-n) short range correlations in terms of the short range (p-n) correlations and ultrarelativistic Coulomb (p-e) interaction. We find that these correlations lead to holes in (e...

Precision measurements of neutron decay offer complementary access to particle physics at small distance scales or high energies. In particular they allow tests of the V-A structure of the weak interaction. Among many experimental activities which are ongoing around the world we present two new experiments which are planned or studied for the near future. While the neutron lifetime still bears ...

The beta-decay of the neutron, n + p + e+ Ce, either in its free or its bound state, is the most elementary of the semi-leptonic weak hadron decays, and, along with muon decay, is the prime source of experimental information underpinning the V-A description of weak interactions. We review its role in the context of the standard model of particle physics, and discuss the significance of both the...

There exists both theoretical and observational evidence that the magnetic field decay in neutron stars may proceed in a pronounced non–linear way during a certain episode of the neutron star's life. In the presence of a strong magnetic field the Hall–drift dominates the field evolution in the crust and/or the superfluid core of neutron stars. Analysing observations of P and ˙ P for sufficientl...

Radiative corrections to the neutron β−decay within the Standard Model. Abstract Starting with the basic Lagrangian of the Standard Model, the radiative corrections to the neutron β−decay are acquired. The electroweak interactions are consistently taken into consideration amenably to the Weinberg-Salam theory. The effect of the strong quark-quark interactions on the neutron β−decay is parameter...
