Charming new B-physics [PDF]

open access: yesJournal of High Energy Physics, 2020
We give a comprehensive account of the flavour physics of Beyond-Standard-Model (BSM) effects in b → c c ¯ $$ \overline{c} $$ cs transitions, considering the full set of 20 four-quark operators.

b Physics [PDF]

open access: yesAIP Conference Proceedings, 1998
A summary of the most recent and important measurements in b physics is presented. The production of beauty particles in Z decays, b quark couplings, lifetimes, B0-B0bar oscillations, semileptonic b decays and studies of the number of charm quarks produced in b decays are reviewed.

B PHYSICS AT LHCb [PDF]

open access: yesInternational Journal of Modern Physics A, 2008
LHCb is a dedicated detector for b physics at the LHC (Large Hadron Collider). In this paper we present a concise review of the detector design and performance together with the main physics goals and their relevance for a precise test of the Standard Model and search of New Physics beyond it.

B physics and extra dimensions [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2003
We compute the dominant new physics contributions to the processes Z -> b b and B - B in the context of two representative models with extra dimensions. The main thrust of the calculations focuses on how to control the effects of the infinite tower of Kaluza-Klein modes inside the relevant one-loop diagrams.

Measurement of the CP-violating phase ϕs in the Bs0→J/ψϕ(1020)→μ+μ−K+K− channel in proton-proton collisions at s=13TeV

open access: yesPhysics Letters B, 2021
The CP -violating weak phase ϕs and the decay width difference ΔΓs between the light and heavy Bs0 mass eigenstates are measured with the CMS detector at the LHC in a sample of 48500reconstructed Bs0→J/ψϕ(1020)→μ+μ−K+K− events.

Epitaxial growth of V2O3 thin films on Si(111) by molecular beam epitaxy

open access: yesResults in Physics, 2023
Vanadium sesquioxide (V2O3) is a strongly correlated electron material exhibiting two distinct metal–insulator transitions that can be tuned via strain, doping, or pressure, making it an interesting material for new-generation sensors or smart devices ...

Tuning the spin texture of graphene with size-specific Cu n clusters: a first-principles study

open access: yesJPhys Materials, 2023
The size dependent interaction of Cu _n ( n = 1‒5) clusters with pristine and defective (C-vacancy) graphene is studied by employing density functional theory.

Impact of b → c measurements on Λb→pτν¯ decay in U1 leptoquark model

open access: yesNuclear Physics B, 2023
The measurements of several lepton flavor universality (LFU) violating observables in the decays induced by the quark level transition b→cτν¯ provide an inkling of plausible physics beyond the standard model of electroweak interactions.

B physics and quarkonia at CMS

open access: yesEPJ Web of Conferences, 2015
Selected recent results on B physics and quarkonia are presented. These include a determination of the CP-violating phase ϕs and the decay width difference ΔΓs of the light and heavy Bs states with Bs → J/ψ Φ(1020), prompt double-differential production ...
