LHCb detector performance [PDF]

open access: yes, 2014
The LHCb detector is a forward spectrometer at the Large Hadron Collider (LHC) at CERN. The experiment is designed for precision measurements of CP violation and rare decays of beauty and charm hadrons.

Search for CP violation in D s + $$ {D}_{(s)}^{+} $$ → K − K + K + decays

open access: yesJournal of High Energy Physics, 2023
A search for direct CP violation in the Cabibbo-suppressed decay D s + $$ {D}_s^{+} $$ → K − K + K + and in the doubly Cabibbo-suppressed decay D + → K − K + K + is reported.

Measurement of CP asymmetries in D s + → η π + $$ {D}_{(s)}^{+}\to \eta {\pi}^{+} $$ and D s + → η ′ π + $$ {D}_{(s)}^{+}\to {\eta}^{\prime }{\pi}^{+} $$ decays

open access: yesJournal of High Energy Physics, 2023
Searches for CP violation in the decays D s + → η π + $$ {D}_{(s)}^{+}\to \eta {\pi}^{+} $$ and D s + → η ′ π + $$ {D}_{(s)}^{+}\to {\eta}^{\prime }{\pi}^{+} $$ are performed using pp collision data corresponding to 6 fb −1 of integrated luminosity ...

Charm physics prospects at Belle II [PDF]

open access: yes, 2018
Belle II is a major upgrade of the Belle experiment and will operate at the $B$-factory SuperKEKB in Japan. Here we discuss the expected sensitivity of Belle II for $D^0 - \bar{D}^0$ mixing and $CP$ violation measurements in the charm sector, which will ...

Search for direct CP violation in D 0 →h - h + modes using semileptonic B decays [PDF]

open access: yes, 2013
A search for direct CP violation in D0 -> h- h+ (where h=K or pi) is presented using data corresponding to an integrated luminosity of 1.0 fb^-1 collected in 2011 by LHCb in pp collisions at a centre-of-mass energy of 7 TeV.

ΔA CP within the Standard Model and beyond

open access: yesJournal of High Energy Physics, 2019
In light of the recent LHCb observation of CP violation in the charm sector, we review standard model (SM) predictions in the charm sector and in particular for ΔA CP.

Higgs boson decay to charm pair at full one-loop level in the MSSM with flavour violation

open access: yes, 2014
We study the decay of the lightest neutral Higgs boson to a charm quark pair at full one-loop level in the MSSM with non-minimal quark flavour violation (QFV). In the numerical analysis we consider mixing between the second and the third squark generation and all relevant constraints from B meson data are taken into account.

Assessing lepton-flavour non-universality from B →K∗ℓℓ angular analyses

open access: yesJournal of High Energy Physics, 2016
The B → K∗μμ decay exhibits deviations with respect to Standard Model expectations and the measurement of the ratio RK hints at a violation of lepton-flavour universality in B → Kℓℓ transitions. Both effects can be understood in model-independent fits as

Changes in Alcohol Retail Laws and Foot Traffic at Liquor Stores

open access: yesApplied Economic Perspectives and Policy, EarlyView.
ABSTRACT We study how expanding alcohol availability at grocery and convenience stores affects consumer traffic in liquor stores by leveraging recent changes in state‐level alcohol distribution laws in a difference‐in‐difference quasi‐experimental design.

How can welfare regime and production regime theories explain differences in schools’ ability grouping policies? A comparative study using the PISA school survey

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Research evidence is mixed on the consequences of ability grouping policies, but most research has found an overrepresentation of disadvantaged social demographics in low‐ability groups. However, researchers have neglected to explain why ability grouping policies vary between countries.
