Charm mixing in the Standard Model and beyond [PDF]

open access: yes, 2006
The motivation most often cited in searches for D0-anti-D0 mixing and CP-violation in charm system lies with the possibility of observing a signal from New Physics which dominates that from the Standard Model. We review recent theoretical predictions and

Measurement of the cross section of e + e − → ηπ + π − at center-of-mass energies from 3.872 GeV to 4.700 GeV

open access: yesJournal of High Energy Physics, 2022
Using data samples with an integrated luminosity of 19 fb −1 at twenty-eight center-of-mass energies from 3.872 GeV to 4.700 GeV collected with the BESIII detector at the BEPCII electron-positron collider, the process e + e − → ηπ + π − and the ...

Tagging new physics with charm

open access: yesJournal of High Energy Physics, 2017
We propose a new variable, the charm fraction, for collider searches for new physics. We analyze this variable in the context of searches for simplified supersymmetry models with squarks, the gluino, and the bino, assuming that only the lightest ...

Measurement of the branching fractions of the singly Cabibbo-suppressed decays Λ c + → p η $$ {\Lambda}_{\textrm{c}}^{+}\to \textrm{p}\eta $$ and Λ c + → p ω $$ {\Lambda}_{\textrm{c}}^{+}\to \textrm{p}\omega $$

open access: yesJournal of High Energy Physics, 2023
Based on 4.5 fb −1 e + e − collision data collected with BESIII detector at seven energy points between 4.600 and 4.699 GeV, the branching fractions for Λ c + → pη $$ {\Lambda}_c^{+}\to p\eta $$ and Λ c + → pω $$ {\Lambda}_c^{+}\to p\omega $$ were ...

Recent results from CLEO collaboration [PDF]

open access: yes, 2001
Recent CLEO results on beauty and charm meson decays presented at the International Conference on Flavor Physics (ICFP2001) are discussed. The results include exclusive rare B decays (B to PP, PV, VV, \phiK^(*), l^+l^-K^(*)), inclusive b to s \gamma, and

The PANDA experiment: physics goals and experimental setup

open access: yesEPJ Web of Conferences, 2014
PANDA (antiProton ANnihilation at DArmstadt) is an experiment that will run at the GSI laboratory, Darmstadt, Germany, in 2019. A high intensity antiproton beam with momentum up to 15 GeV/c will collide on a fixed proton target (pellet target or jet ...

BRIEF REVIEW OF CHARM PHYSICS [PDF]

open access: yesModern Physics Letters A, 2012
Charm physics has attracted increased attention after the first evidence for charm mixing was observed in 2007. The level of attention has risen sharply after LHCb reported first evidence for CP violation in the charm sector. Neither mixing nor CP violation have been established by a single unambiguous measurement to date.

Λ c + $$ {\Lambda}_c^{+} $$ polarimetry using the dominant hadronic mode

open access: yesJournal of High Energy Physics, 2023
The polarimeter vector field for multibody decays of a spin-half baryon is introduced as a generalisation of the baryon asymmetry parameters. Using a recent amplitude analysis of the Λ c + $$ {\Lambda}_c^{+} $$ → pK − π + decay performed at the LHCb ...

Status of Charm Flavor Physics [PDF]

open access: yesInternational Journal of Modern Physics A, 2005
The role of charm in testing the Standard Model description of quark mixing and CP violation through measurements of lifetimes, decay constants and semileptonic form factors is reviewed. Together with Lattice QCD, charm has the potential this decade to maximize the sensitivity of the entire flavor physics program to new physics and pave the way for ...
