Charming new B-physics

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.

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 ...

Future Physics Programme of BESIII [PDF]

open access: yesChinese Physics C, High Energy Physics & Nuclear Physics, 2019
There has recently been a dramatic renewal of interest in hadron spectroscopy and charm physics. This renaissance has been driven in part by the discovery of a plethora of charmonium-like XYZ states at BESIII and B factories, and the observation of an ...

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 ...

Observation of the decay B+→ψ(2S)ϕ(1020)K+ in pp collisions at s=8TeV

open access: yesPhysics Letters B, 2017
The decay B+→ψ(2S)ϕ(1020)K+ is observed for the first time using data collected from pp collisions at s=8TeV by the CMS experiment at the LHC, corresponding to an integrated luminosity of 19.6fb−1.

Quantum mechanisms for selective detection in complex gas mixtures using conductive sensors

open access: yesScientific Reports, 2023
In this paper, we consider new quantum mechanisms for selective detection in complex gaseous media which provide the highest possible efficiency of quantum sensors and for the first time analyze their nature. On the basis of these quantum mechanisms, the

A facility to search for hidden particles at the CERN SPS: the SHiP physics case [PDF]

open access: yesReports on progress in physics. Physical Society, 2015
This paper describes the physics case for a new fixed target facility at CERN SPS. The SHiP (search for hidden particles) experiment is intended to hunt for new physics in the largely unexplored domain of very weakly interacting particles with masses ...
