Charm Physics at HERA

open access: yesAIP Conference Proceedings, 2009
Recent results on charm physics from the HERA ep collider experiments H1 and ZEUS are described. Cross section measurements are made in photoproduction and deep‐inelastic scattering (DIS) using a variety of techniques. The DIS results are used to extract the charm contribution to the proton structure function.

Feasibility of measuring the magnetic dipole moments of the charm baryons at the LHC using bent crystals

open access: yesJournal of High Energy Physics, 2017
In this paper we revisit the idea of measuring the magnetic dipole moments of the charm baryons and, in particular, of Λ c + by studying the spin precession induced by the strong effective magnetic field inside the channels of a bent crystal.

Drag Effects in Charm Photoproduction [PDF]

open access: yes, 1998
We have refined a model for charm fragmentation at hadron colliders. This model can also be applied to the photoproduction of charm. We investigate the effect of fragmentation on the distribution of produced charm quarks.

Counterion Dependent Side‐Chain Relaxation Stiffens a Chemically Doped Thienothiophene Copolymer

open access: yesAdvanced Functional Materials, EarlyView.
Oxidation of a thienothiophene copolymer, p(g3TT‐T2), via different doping strategies and dopant molecules resulted in materials with similar oxidation levels and a high electrical conductivity of ≈100 S cm−1. However, mechanical properties varied significantly, with sub‐glass transition temperatures and elastic moduli spanning from –44°C to –3°C and ...

Selection of LHCb Physics Results

open access: yesEPJ Web of Conferences, 2013
LHCb is a dedicated flavour physics experiment at the LHC searching for physics beyond the Standard Model through precision measurements of CP-violating observables and the study of very rare decays of beauty- and charm-flavoured hadrons. In this article

CP violation in three-body B decays: a model ansatz

open access: yesJournal of High Energy Physics, 2020
The mechanism of CP violation remains one of the puzzles in particle physics. Key to understanding this phenomenon are nonleptonic B decays, especially multibody decays which exhibit large CP asymmetries in various regions of phase space.

Observation of the doubly Cabibbo-suppressed decays D + → K + π 0 π 0 and D + → K + π 0 η

open access: yesJournal of High Energy Physics, 2022
By analyzing e + e − annihilation data corresponding to an integrated luminosity of 2.93 fb −1 collected at the center-of-mass energy of 3.773 GeV with the BESIII detector, we report the first observations of the doubly Cabibbo-suppressed decays D + → K +

CP violation in charm and beauty decays at LHCb

open access: yes, 2012
LHCb is a dedicated heavy flavour physics precision experiment at the LHC searching for New Physics (NP) beyond the Standard Model (SM) through the study of very rare decays of beauty and charm-flavoured hadrons and precision measurements of CP-violating

Covalent Organic Frameworks for Photocatalytic CO2 Reduction: Metal Integration Principles, Strategies and Functions

open access: yesAdvanced Functional Materials, EarlyView.
Covalent organic frameworks (COFs) with metals have been recognized as versatile platforms for photocatalytic CO2 reduction (CO2PRR). Herein, an overview of metal integration strategies for COFs is systematically summarized. Regulatory mechanisms and structure–activity relationships between metal integration and COF‐based CO2PRR are emphasized.
