1. Upgrade of the NA61/SHINE Facility beyond 2020 for an Expanded Physics Programme

Author

Dag Larsen and on behalf of the NA61/SHINE collaboration

Subjects
NA61/SHINE, upgrade, open charm, silicon detector, time projection chamber, CERN long shutdown 2, Elementary particle physics, QC793-793.5
Abstract

The NA61/SHINE experiment studies hadron production in hadron-hadron, hadron-nucleus and nucleus-nucleus collisions. The physics programme includes the study of the onset of deconfinement and search for the critical point as well as reference measurements for neutrino and cosmic ray experiments. For strong interactions, future plans are to extend the programme of study of the onset of deconfinement by measurements of open-charm and possibly other short-lived, exotic particle production in nucleus-nucleus collisions. This new programme is planned to start after 2020 and requires upgrades to the present NA61/SHINE detector setup. Besides the construction of a large acceptance silicon detector, a 10-fold increase of the event recording rate is foreseen, which will necessitate a general upgrade of most detectors.

2. Prøysens varme ironi

Abstract

Det er visst blitt et forskningsfaktum: Et barn ler ca fire hundre ganger pr dag. En voksen som regel ti. Studien ble i fullt alvor publisert av British Journal of Development Psychology (Recchia m.fl. 2010). Den viser også at barn helt ned i fire års alder kan forstå at en kommentar er ment ironisk og ikke bokstavelig. Jeg innrømmer at jeg ble glad da jeg leste dette. Forfattere har nemlig fått høre det lenge av forskere, kritikere, forleggere og andre. At barn har vondt for å skjønne ironi. At forfattere må være varsom med å bruke det, for det er sannsynlig at bare voksne vil le. Men da er det som vi hører et leende barn si: «Jammen, de voksne må da få lov til å le litt, de også!» Det samme sa Alf Prøysen, som var kjent radiostemme og forfatter for norske barn fra tidlig femtitall fram til i år, der hans hundreårsdag er blitt feiret. Bøkene hans om Teskjekjerringa nådde ut til barn i mange land. Prøysen tok i bruk sin hjemlige dialekt i skriftspråk, tale og sang, og ble svært populær (og er det ennå) blant barn og voksne, med sin unike kombinasjon av jordnær folkelighet og kunstnerisk presisjon.

Abstract

Inclusive production of $\Lambda$-hyperons was measured with the large acceptance NA61/SHINE spectrometer at the CERN SPS in inelastic p+p interactions at beam momentum of 158~\GeVc. Spectra of transverse momentum and transverse mass as well as distributions of rapidity and x$_{_F}$ are presented. The mean multiplicity was estimated to be $0.120\,\pm0.006\;(stat.)\,\pm 0.010\;(sys.)$. The results are compared with previous measurements and predictions of the EPOS, UrQMD and FRITIOF models.
