Physics programme of ALICE 3: A next-generation heavy-ion detector for LHC Run 5 and beyond [PDF]

open access: yesEPJ Web of Conferences
The ALICE Collaboration is designing a completely new apparatus, ALICE 3, for the LHC Runs 5 and 6. The detector comprises a large pixel-based tracking system covering eight units of pseudorapidity, complemented by various particle identification systems

Measurements with doubly-charmed hadrons in LHCb [PDF]

open access: yesEPJ Web of Conferences, 2019
The LHCb experiment has been collecting large amounts of charm data, making it possible to perform precise measurements and search for rare particles. In 2017, the LHCb collaboration reported the first observation of the doubly charmed baryon, the Ξcc++$

Charm physics [PDF]

open access: yesAIP Conference Proceedings, 1989
The status of charm physics with emphasis on recent high statistics results from fixed target experiments is presented. The topics covered include charm production, D/sup 0//bar D//sup 0/ mixing, charm baryons and excited states such as the D**. Also reviewed are charm decays: hadronic, leptonic as well as semileptonic. Finally, we take a brief look at

CHARM PHYSICS AT HERA

open access: yesInternational Journal of Modern Physics: Conference Series, 2014
Recent measurements of charm production at HERA are presented. They include measurements of charm fragmentation fractions, of charm production in DIS and of inelastic and exclusive J/ψ photoproduction. Charm measurements have been combined and analysed in the framework of a QCD fit to inclusive and charm data.

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

Charm physics

open access: yesThe European Physical Journal Special Topics
AbstractWe review recent developments in charm physics, focusing on the physics of charmed mesons. We discuss recent progress in charm spectroscopy and the multitude of mesonic and baryonic exotic states containing charm quarks. We review searches for new physics with charmed mesons with rare decays.

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 ...

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 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 ...
