Chemical element transport in stellar evolution models [PDF]

Royal Society Open Science, 2017
Stellar evolution computations provide the foundation of several methods applied to study the evolutionary properties of stars and stellar populations, both Galactic and extragalactic.

An analysis of B_{d,s} mixing angles in presence of New Physics and an update of Bs -> K0* anti-K0*

, 2011
We discuss a simple approach to measure the weak mixing angles phi_s and phi_d of the Bs and Bd systems in the presence of New Physics. We present a new expression that allows one to measure directly the New Physics mixing angles if New Physics ...

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.

The Nature of Massive Neutrinos

Advances in High Energy Physics, 2013
The compelling experimental evidences for oscillations of solar, reactor, atmospheric, and accelerator neutrinos imply the existence of 3-neutrino mixing in the weak charged lepton current.

Neutrinos in a Minimal 3-3-1 Model

Frontiers in Physics, 2022
In this work, we present a general review of neutrino physics in the minimal 331 model. New gauge and scalar interactions are present, with violation of both flavor and lepton numbers.

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.

Experimental Status of $B$ Physics

, 2006
A short summary is given of the current status of B physics. Reasons for physics beyond the Standard Model are discussed. Constraints on New Physics are given using measurements of B mixing, Bs mixing, and CP violation, along with |Vub. Future goals, and

Improved sensitivities of ESSνSB from a two-detector fit

Journal of High Energy Physics, 2023
We discuss the improvement of the sensitivity of ESSνSB to the discovery of CP violation and to new neutrino physics which can be obtained with a two-detector fit of the data of the near and far detectors. In particular, we consider neutrino non-standard

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.

Searching for New Physics in $D^0\rightarrow \mu^+\mu^-,\; e^+e^-, \;\mu^{\pm}e^{\mp}$ at BES and/or Super Charm-Tau Factory

, 2014
In contrast with $B^0-\bar B^0$, $B_s-\bar B_s$ mixing where the standard model (SM) contributions overwhelm that of new physics beyond standard model (BSM), a measured relatively large $D^0-\bar D^0$ mixing where the SM contribution is negligible ...
