Towards new frontiers with B → πK decays

open access: yesPhysics Letters B, 2018
Exploring correlations between the CP asymmetries of Bd0→π0KS following from an isospin relation, we uncover new tensions with the Standard Model in data for neutral B→πK decays.

B PHYSICS AND CP VIOLATION [PDF]

open access: yesFundamental Interactions, 2004
These lectures provide a basic overview of topics related to the study of CP Violation in B decays. In the first lecture, I review the basics of discrete symmetries in field theories, the quantum mechanics of neutral but flavor-non-trivial mesons, and the classification of three types of CP violation.

Electromigration-induced resistance switching in indented Al microstrips

open access: yesNew Journal of Physics, 2019
Non-volatile resistive memory cells are promising candidates to tremendously impact the further development of Boolean and neuromorphic computing. In particular, nanoscale memory-bit cells based on electromigration (EM)-induced resistive switching in ...

Imprints of new physics operators in the semileptonic B→a1(1260)ℓ−ν¯ℓ process in SMEFT approach

open access: yesPhysics Letters B
At present, there are several measurements of B decays that exhibit discrepancies with the predictions of the Standard Model, and suggest the presence of new physics in b→s and b→c(u) quark level transitions.

Vortices in a wedge made of a type-I superconductor

open access: yesNew Journal of Physics, 2015
Using the time-dependent Ginzburg–Landau approach, we analyze vortex states and vortex dynamics in type-I superconductor films with a thickness gradient in one direction.

Constraints on new physics from radiative B decays

open access: yesJournal of High Energy Physics, 2017
A new phase for the measurements of radiative decay modes in b → s transitions has started with new measurements of exclusive modes by LHCb and with Belle-II showing distinctive promises in both inclusive and exclusive channels.

Measurement of the Higgs boson production via vector boson fusion and its decay into bottom quarks in proton-proton collisions at s $$ \sqrt{s} $$ = 13 TeV

open access: yesJournal of High Energy Physics
A measurement of the Higgs boson (H) production via vector boson fusion (VBF) and its decay into a bottom quark-antiquark pair ( b b ¯ $$ \textrm{b}\overline{\textrm{b}} $$ ) is presented using proton-proton collision data recorded by the CMS experiment ...

open access: yesJournal of High Energy Physics
Measurements of inclusive and normalized differential cross sections of the associated production of top quark-antiquark and bottom quark-antiquark pairs, t t ¯ b b ¯ $$ \textrm{t}\overline{\textrm{t}}\textrm{b}\overline{\textrm{b}} $$ , are presented ...
