Search for Chargino-Neutralino Pair Production at CDF

We present the results of a search for associated production of the lightest chargino and next-to-lightest neutralino using 1 fb$^{-1}$ of $\sqrt s$ = 1.96 TeV p$\rm \bar p$ data collected with the CDF detector at the Tevatron. We combine the results of several multi-lepton final states to set upper limits on the cross section times branching ratio for chargino-neutralino production as a function of the chargino mass.Comment: Submitted for the SUSY07 proceedings, 3 pages, LaTeX, 6 eps figure

Parents’ perspectives on preparing for parenthood: a qualitative study on Greenland’s universal parenting programme MANU 0–1 year

Background The transition to parenthood has received increasing attention in research, partly due to evidence pointing out the crucial developmental period of a child’s first thousand days. Parenting programmes aim to prepare and support families in their transition and distress. For a programme to be implemented successfully it is important to consider parents’ needs and resources. Bringing parents’ perspectives and experiences to the forefront of the implementation of the Greenlandic parenting programme MANU 0–1 Year (MANU) is important for determining if the programme can meet its aim of contributing to thriving families. This study aims to investigate how parents’ notions and experiences of parenthood are reflected and challenged in MANU. Method Data were collected in three of Greenland’s five municipalities. Qualitative interviews were held with 38 mothers and 12 fathers either individually or as couples: a total of 40 interviews. Additionally, a Sharing Circle with three fathers was held. Interviews were in Greenlandic or Danish. A thematic, inductive analysis was applied. Results In their transition to parenthood, participants experienced a reprioritisation of their life and changes in their network. It is important to parents that their child experiences security and care, and participants describe this in contrast to their own childhood. Community is the most important value in child-rearing. Conversations and advice from family members and friends are mentioned as a means to prepare for birth and parenthood. Additionally, conversations with midwives and MANU sessions were also used for preparation. Parents appreciated learning from and listening to other parents in MANU sessions. However, accessing MANU depends on the individual parent’s interest and ability to attend sessions. Conclusions Parents’ notions and experiences of parenthood are addressed in the programme, but the use of MANU depends on the parents’ attendance and how it is organised and locally offered. The study suggests that MANU has the possibility to create a space for parents to reflect and prepare. However, for MANU to be universal as intended and to reach both mother and father the facilitation of sessions could be revisited

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
