The Formalism of Generalized Contexts and Decay Processes
The formalism of generalized contexts for quantum histories is used to investigatethe possibility to consider the survival probability as the probability of no decay property at a given time conditional to no decay property ...
Nonmesonic weak decay of charmed hypernuclei
(Iop Publishing Ltd, 2018-01-01)
We present a study of the nonmesonic weak decay (NMWD) of charmed hypernuclei using a relativistic formalism. We work within the framework of the independent particle shell model and employ a (pi, K) one-meson-exchange ...
COPPER ANCHORED TO AMINO-GROUP FUNCTIONALIZED SILICA GEL AS WOOD PRESERVATIVE AGAINST BROWN-ROT DECAY

Dynamics of hypernuclear nonmesonic weak decay
Simple and coincidence spectra of the NM weak decay of light hypernuclei have been evaluated in a systematic way for the first time. We have only considered 1N induced processes, neglecting entirely the events induced by ...
Meson Decays and Physics Beyond Standard Model
In this thesis we discuss possible effects of new physics beyond the Standard Model (SM) associated with high energy scales. We make special emphasis on their manifestations in low energy processes such as meson decays. ...
Search for new physics in rare top decays: t ¯ t spin correlations and other observables
(American Physical Society, 2014-11)
In this paper we study new-physics contributions to the top-quark decay t → bbc. We search for ways of detecting such new physics via measurements at the LHC. As top quarks are mainly produced at the LHC in tt production ...
Dispersal traits drive the phylogenetic distance decay of similarity in Neotropical stream metacommunities
Aim: The drivers of phylogenetic beta diversity include both local processes (e.g. environmental filtering) and regional processes (e.g. dispersal limitation). The role of environmental filtering can be investigated more ...
Matrix elements of four-quark operators and Delta L= 2 hyperon decays
(Amer Physical Soc, 2013-02)
The study of neutrinoless double beta decays of nuclei and hyperons requires the calculation of hadronic matrix elements of local four-quark operators that change the total charge by two units. Using a low energy effective ...
Relativistic model for the nonmesonic weak decay of single-lambda hypernuclei
(Iop Publishing, 2016-03-22)
Having in mind its future extension for theoretical investigations related to charmed nuclei, we develop a relativistic formalism for the nonmesonic weak decay (NMWD) of single-λ hypernuclei in the framework of the ...
