Discovering Technicolor at Hadron Colliders

Strategies are presented for discovering light, color-singlet technipions (pi_T) produced in association with a vector boson through s-channel technirho production, at the Tevatron and LHC. Signal and W+jets background were simulated including detector effects. Tagging of b-quarks from the pi_T -> bb decay is found to be important to reduce the W+jets background. Kinematic properties of signal and background events are significantly different and simple cuts can be used to further improve the signal to background ratio.Comment: 4 pages, 6 figures, LaTeX; to appear in the Proceedings of the 1996 DPF/DPB Summer Study (Snowmass 1996

QCD at the Tevatron: Status and Prospects

I shall review the present status of Tevatron QCD studies, focusing on the production of jets, vector bosons, photons and heavy quarks. In general there is good agreement between the results of current calculational tools and the experimental data. The major areas of discrepancy arise when the input parton distributions become uncertain (for example, jets at high $E_T$) or when the momentum scales become relatively small (for example, $b$ production at low $p_T$). We can look forward to continued improvement in both calculations and measurements over the next decade. However, fully exploiting the power of the data will require considerable work, both from the experimentalists who must understand and publish all the systematic errors and their correlations, and from the phenomenologists who must understand the level of uncertainty in their calculations and in the parton distributions.Comment: Presented at the Fifth International Symposium on Radiative Corrections (RADCOR 2000), Carmel, CA, September 11-15, 2000.

Future Accelerators (?)

I describe the future accelerator facilities that are currently foreseen for electroweak scale physics, neutrino physics, and nuclear structure. I will explore the physics justification for these machines, and suggest how the case for future accelerators can be made.Comment: Presented at the Conference on the Intersections of Particle and Nuclear Physics (CIPANP 2003), New York City, May 200

Tests of Perturbative QCD and Jet Physics

I describe the current status of tests of perturbative QCD, using measurements of jet, photon, weak boson and heavy flavor production from the Tevatron, LEP and HERA. Measurements of the strong coupling constant are described, and I conclude with a "wish list" for the future.Comment: To appear in the Proceedings of the XIX International Symposium on Lepton and Photon Interactions at High Energies (LP99), Stanford University, August 1999 Replaced version corrects Ref [31] and adds an additional plot to Fig.2

Can a light technipion be discovered at the Tevatron if it decays to two gluons?

In multiscale and topcolor-assisted models of walking technicolor, light, spin-one technihadrons can exist with masses of a few hundred GeV; they are expected to decay as rho_T -> W pi_T. For technirho masses ~200 GeV and technipion masses ~100 GeV, the process pbar p -> rho_T -> W pi_T has a cross section of about a picobarn at the Tevatron. We demonstrate the detectability of this process with simulations appropriate to Run II conditions, for the challenging case where the technipion decays dominantly into two gluons.Comment: 11 pages, LaTeX, including figure

PRESCRIPTION OF SODIUM VALPROATE AS A MOOD STABILISER IN PREGNANCY

This essay was submitted for the Royal College of Psychiatry’s perinatal psychiatry medical student essay prize in 2017. The essay considers the choices available to women with bipolar disorder who become pregnant while taking sodium valproate to treat mania or for mood stabilisation. The implications of three options are considered: to stop all treatment, to switch to a different mood stabiliser or to continue on sodium valproate. The implications for the fetus, on the mother’s wellbeing and the ethics of patient choice are discussed. Background: Pregnancy can be especially challenging for women with bipolar disorder, predominantly because of the heightened probability of relapse, potential fetal harm caused by bipolar medication, and a 250-fold risk of puerperal psychosis compared to the general population. Sodium valproate is a known teratogen, and is discouraged in pregnancy, but what choice is open to women who rely on this medication to stabilise their mood? Conclusions: The large majority of women of childbearing age with bipolar disorder should not be prescribed sodium valproate as the risks to the unborn fetus far outweigh the benefits of the medication, as other drugs have similar if not better efficacy to stabilize the mother’s mood, with lower risks to the fetus. In the small minority of women for whom valproate may be the only effective treatment, she must be fully informed of the teratogenic and neurodevelopmental risks, as well as the ways in which the pregnancy can be managed to reduce such risks

Imagining space and place: the representation of Africa through image and text in Andrew Lang's Fairy Books (1889-1910)

This dissertation examines the representation of Africa and Africans in Andrew Lang's Fairy Books (1889-1910) considered to be the first global anthologies of fairy tales. Published at the heyday of the British Empire, they presented Africa and Europe alongside each other to the Victorian-era British audience of the time. As an appraisal of Lang's role as curator/editor, the study interrogates the books as containing representations of Africa from outside of Africa. While the inclusion of tales originating in Africa makes steps towards acknowledging an African story tradition independent of Europe, the editing process shaped the tales through European tale traditions and coloured by colonial perceptions of Africa. Lang's collaborative team of predominantly female translators/adaptors, as both Victorians and women, shaped the texts through their own sensitivities. The images, also created through one pictorial lens by Henry Justice Ford, were informed by imagination rather than fact, and the images were embraced for artistic merit rather than accuracy. The dissertation explores how the representation interplay and slippage between the image and text in this colonial project of ‘fairy tale' created a complex and contradictory single narrative of Africa and Africans. From this new assessment of Andrew Lang's Fairy Books (1889-1910), the dissertation formulates the argument of the cartographic imagination as fairy tale by comparing both the visual and textual components of fairy stories and maps, in addition to how they operate, how they are assembled, and their roles as agents of socialisation. These visual and textual components of fairy stories and maps were two forms of representation that were both used in the 19th century to socialise African people into being ‘productive' colonised citizens. This study models new approaches – cartographic imagination as fairy tale and the image-text relationship – to reinvestigate Victorian representations of Africa and bring a more nuanced understanding and fresh perspective to this area of scholarship
