Isolated photon and photon+jet production at NNLO QCD accuracy and the ratio R13/8γR_{13/8}^\gamma

We discuss different approaches to photon isolation in fixed-order calculations and present a new next-to-next-to-leading order (NNLO) QCD calculation of $R_{13/8}^\gamma$, the ratio of the inclusive isolated photon cross section at 8 TeV and 13 TeV, differential in the photon transverse momentum, which was recently measured by the ATLAS collaboration.Comment: 4 pages, 1 figure.

Identifying the transporters of different flavonoids in plants

We recently identified a new component of flavonoid transport pathways in Arabidopsis. The MATE protein FFT (Flower Flavonoid Transporter) is primarily found in guard cells and seedling roots, and mutation of the transporter results in floral and growth phenotypes. The nature of FFT’s substrate requires further exploration but our data suggest that it is a kaempferol diglucoside. Here we discuss potential partner H+-ATPases and possible redundancy among the close homologues within the large Arabidopsis MATE family

Z+jet production at NNLO

We give a brief overview of our calculation of the next-to-next-to-leading order (NNLO) QCD corrections to Z+jet production in hadronic collisions. Phenomenological results are presented which comprise various differential distributions for 8 TeV proton-proton collisions. A significant reduction of the scale uncertainties is observed throughout as we move from NLO to NNLO. We further discuss how this calculation can be used to describe the inclusive Z-boson production at large transverse momentum. To this end, the theory prediction is compared to the measurements performed by the ATLAS and CMS collaborations at a centre-of-mass energy of 8 TeV. Here, the inclusion of NNLO QCD effects are found to result in a substantial improvement in the agreement between theory and data for the normalised distributions.Comment: 8 pages, 5 figures, to appear in the proceedings of Loops and Legs in Quantum Field Theory, 24-29 April 2016, Leipzig, German

Let\u27s Talk: An Analysis of the Psychological and Emotional Impacts of the Police Talk on Black Children

The ‘Talk’ is a conversation (or series of conversations) that Black children receive from parents, grandparents, and other guardians and caretakers in their life. The conversation consists of informing them on behaviors to adopt as well as a script to recite should they encounter the police or any other agent of the law. Very little research has been done on the Talk yet alone the impact it has on Black children. Pulling from research on racial socialization, moral development, and the impact of racism on one’s well being, the purpose of this study is to explore how Black children are psychologically impacted by law enforcement and other agents of the law. Specifically this study will explore how the Talk can impact perception of law enforcement. This study will consist of qualitative and quantitative methods as participants will participate in an interview as well as complete measures of wellbeing, anxiety, trust in the legal system and perception of law enforcement. Results are predicted to show that Black children have negative perceptions of the legal system and feelings of law enforcement. Furthermore, it is expected that with age, children will comprehend the complexities and emotional circumstances that go into understanding and discussing the Talk. This research has the potential to show the psychological effects of police brutality and police violence beyond the specific interaction
