First measurement of Ωc0 production in pp collisions at s=13 TeV

The inclusive production of the charm–strange baryon 0 c is measured for the first time via its hadronic √ decay into −π+ at midrapidity (|y| <0.5) in proton–proton (pp) collisions at the centre-of-mass energy s =13 TeV with the ALICE detector at the LHC. The transverse momentum (pT) differential cross section multiplied by the branching ratio is presented in the interval 2 < pT < 12 GeV/c. The pT dependence of the 0 c-baryon production relative to the prompt D0-meson and to the prompt 0 c-baryon production is compared to various models that take different hadronisation mechanisms into consideration. In the measured pT interval, the ratio of the pT-integrated cross sections of 0 c and prompt + c baryons multiplied by the −π+ branching ratio is found to be larger by a factor of about 20 with a significance of about 4σ when compared to e+e− collisions

Elliptic flow of charged particles at midrapidity relative to the spectator plane in Pb–Pb and Xe–Xe collisions

Measurements of the elliptic flow coefficient relative to the collision plane defined by the spectator neutrons v2{ SP} in collisions of Pb ions at center-of-mass energy per nucleon–nucleon pair √ 2.76 TeV and Xe ions at √ sNN = sNN =5.44 TeV are reported. The results are presented for charged particles produced at midrapidity as a function of centrality and transverse momentum for the 5–70% and 0.2–6 GeV/c ranges, respectively. The ratio between v2{ SP} and the elliptic flow coefficient relative to the participant plane v2{4}, estimated using four-particle correlations, deviates by up to 20% from unity depending on centrality. This observation differs strongly from the magnitude of the corresponding eccentricity ratios predicted by the TRENTo and the elliptic power models of initial state fluctuations that are tuned to describe the participant plane anisotropies. The differences can be interpreted as a decorrelation of the neutron spectator plane and the reaction plane because of fragmentation of the remnants from the colliding nuclei, which points to an incompleteness of current models describing the initial state fluctuations. A significant transverse momentum dependence of the ratio v2{ SP}/v2{4} is observed in all but the most central collisions, which may help to understand whether momentum anisotropies at low and intermediate transverse momentum have a common origin in initial state f luctuations. The ratios of v2{ SP} and v2{4} to the corresponding initial state eccentricities for Xe–Xe and Pb–Pb collisions at similar initial entropy density show a difference of (7.0 ±0.9)%with an additional variation of +1.8% when including RHIC data in the TRENTo parameter extraction. These observations provide new experimental constraints for viscous effects in the hydrodynamic modeling of the expanding quark–gluon plasma produced in heavy-ion collisions at the LHC

Barriers to effective communication across the primary/secondary interface: examples from the ovarian cancer patient journey (a qualitative study)

Effective communication across the primary/secondary interface is vital for the planning and delivery of appropriate patient care throughout the cancer patient journey. This study describes GPs’ views of the communication issues across the primary/secondary interface in relation to ovarian cancer patients using qualitative interviews with purposively sampled general practitioners (GPs) and an audit of hospital medical records of 30 deceased ovarian cancer patients. Issues raised by the GPs related to the content and format of communications, but of most concern was the tardiness. The time lag between dictation and typing letters ranged from 0 to 27 days, with a delay of up to 8 days for signing before transit through various mail systems to the GP. Three stages in the patient journey were characterized by particular issues: (1) in the pre-diagnostic and diagnostic stage was a need for prompt information regarding the results of tests and diagnoses, and clearer guidance on the use of tests and fast-track referrals; (2) in the active treatment phase, when GPs could lose touch with their patients, they needed effective communication in order to provide moral support and crisis management; and (3) when oncology withdrew and the focus of care switched back to the community for the terminal phase, GPs needed information to enable them to pick up the baton of care. There is a need to develop and evaluate interventions aimed at improving the content and speed of communications between secondary and primary care. Such interventions are likely to be complex and might include the greater use of telephone or fax for more selected communications, a review of secretarial support, the use of email, the development of GP designed proformas, the feasibility of patient/carer letter delivery options, nurse-led communication, universal electronic patient records, or a revisiting of the patient-held record
