The physics of mixing: in the chiral quark model [PDF]

Nuclear Physics B, 1997
We compute the BK parameter and the mass difference ΔMLS of the K0−K0 system by means of the chiral quark model. The chiral coefficients of the relevant ΔS = 2 and ΔS = 1 chiral Lagrangians are computed via quark-loop integration. We include the relevant effects of one-loop corrections in chiral perturbation theory.

Stellar cooling bounds on new light particles: plasma mixing effects [PDF]

Journal of High Energy Physics, 2016
Strong constraints on the coupling of new light particles to the Standard Model (SM) arise from their production in the hot cores of stars, and the effects of this on stellar cooling.

Mixing and CP Violation in the Charm System [PDF]

, 2020
In recent years charm physics has undergone a renaissance, one which has been catalysed by an unexpected and impressive set of experimental results from the $B$-factories, the Tevatron and LHCb.

Model-independent analysis of $\bbox{B}$-$\bbox{\bar B}$ mixing and $\bbox{CP}$ violation in $\bbox{B}$ decays

, 1995
We present a framework to analyze effects of new physics beyond the standard model on $B$-$\bar B$ mixing and $CP$ violation in $B$ decays in a model-independent manner.

New physics effects in tree-level decays and the precision in the determination of the quark mixing angle γ [PDF]

, 2014
We critically review the assumption that no new physics is acting in tree-level B-meson decays and study the consequences for the ultimate precision in the direct determination of the Cabibbo-Kobayashi-Maskawa (CKM) angle γ.

Introduction to Charm Physics

, 2015
This paper gives an overview of charm physics. It is a lecture write-up aimed at students with a minimum of prior knowledge in particle physics, but at the same time provides a state-of-the art review of the field.

Possible Effects of $D^0-\bar{D}^0$ Mixing in Weak $B$ Decays

, 1995
$D^0-\bar{D}^0$ mixing at a detectable level requires the presence of new physics and may lead to some observable effects in weak decays of $B$ mesons.

Neutrino-electron scattering: general constraints on Z ′ and dark photon models

Journal of High Energy Physics, 2018
We study the framework of U(1) X models with kinetic mixing and/or mass mixing terms. We give general and exact analytic formulas of fermion gauge interactions and the cross sections of neutrino-electron scattering in such models.

General Quantum Field Theory of Flavor Mixing and Oscillations

Universe, 2021
We review the canonical transformation in quantum physics known as the Bogoliubov transformation and present its application to the general theory of quantum field mixing and oscillations with an arbitrary number of mixed particles with either boson or ...

Theoretical Prospects of Neutrinoless Double Beta Decay

, 2005
The compelling experimental evidences for oscillations of solar and atmospheric neutrinos imply the existence of 3-neutrino mixing in vacuum. We briefly review the phenomenology of 3-neutrino mixing, and the current data on the 3-neutrino mixing ...
