MAXIMAL COMMUTATIVE SUBALGEBRAS INVARIANT FOR CP-MAPS: (COUNTER-)EXAMPLES [PDF]

open access: yesInfinite Dimensional Analysis, Quantum Probability and Related Topics, 2008
We solve, mainly by counterexamples, many natural questions regarding maximal commutative subalgebras invariant under CP-maps or semigroups of CP-maps on a von Neumann algebra. In particular, we discuss the structure of the generators of norm continuous semigroups on [Formula: see text] leaving a maximal commutative subalgebra invariant and show that ...

Can Lorentz invariance violation affect the sensitivity of deep underground neutrino experiment?

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
We examine the impact of Lorentz Invariance Violation (LIV) in measuring the octant of $$\theta _{23}$$ θ23 and CP phases in the context of the Deep Underground Neutrino Experiment (DUNE). We consider the CPT-violating LIV parameters involving $$e - \mu $

A CP-conserving multi-Higgs model without real basis

open access: yes, 2016
Models beyond the Standard Model (bSM) often involve elaborate Higgs sectors, which can be a source of CP-violation. It brings up the question of recognizing in an efficient way whether a model is CP-violating. There is a diffuse belief that the issue of

Who Are the Consumers of European Farmers' Markets? A Cross‐Country Analysis

open access: yesAgribusiness, EarlyView.
ABSTRACT With substantial growth in the number of farmers' markets (FMs) in developed countries, the number of consumers visiting FMs is also increasing. This study comparatively assesses the consumers of FMs in three European countries where FMs traditionally play a distinctive role in food supply chains.

Bound states of a fermion-dyon system

open access: yesEuropean Physical Journal C: Particles and Fields
The bound states of fermions in the external field of an Abelian dyon are studied here both analytically and numerically. Their existence is due to the dyon’s electric charge resulting from a polarization of the fermionic vacuum. The configuration of the

Exploring the effect of Lorentz invariance violation with the currently running long-baseline experiments

open access: yesEuropean Physical Journal C: Particles and Fields, 2020
Neutrinos are the fundamental particles, blind to all kind of interactions except the weak and gravitational. Hence, they can propagate very long distances without any deviation.

Traceability of Agri‐Food Products: The Key to Conscious Trade

open access: yesAgribusiness, EarlyView.
ABSTRACT Globalization and growing concerns about sustainability have led to improvements in product traceability, quality, and sustainability. Traceability contributes to environmental protection and supports sustainable development by fostering transparency in agricultural practices and encouraging the responsible use of resources.

Time-Reversal Invariance Violation in Heavy and in Few-body Nuclei

open access: yes, 2011
Time reversal invariance violating (TRIV) effects in neutron scattering are very important in a search for new physics, being complementary to neutron and atomic electric dipole moment measurements.
