Soft Collinear Effective Theory

In this talk I review soft collinear effective theory. After a discussion of the formalism and properties of the effective field theory, I turn to phenomenology. I present results on color-suppressed B to D decays, and on the Upsilon radiative decay spectrum.Comment: 6 Pages, 3 figures. Parallel session overview talk presented at PANIC05, Particles and Nuclei International Conference, Santa Fe, NM - October 24-28, 200

Anti-Competition Regulation

Looking across the long twentieth century, this article tracks the rise and fall of one form of anti-competition regulation: the certificate of public convenience. Designed to curb “destructive competition” in certain industries, such as transportation and banking, certificate laws prevented firms from entering those industries unless they could convince regulators that they would satisfy an unmet public demand for goods or services. This history highlights how lawmakers used similar techniques in governing infrastructure and finance—two fields that are not often studied together. It also shows that state regulation both prefigured legal change at the federal level and then lagged behind it, suggesting that different dynamics have been in play at each level of governance in devising competition policy over the last century

Production & Decay of Quarkonium

In this talk I review NRQCD predictions for the production of charmonium at the Tevatron. After a quick presentation of the NRQCD factorization formalism for production and decay I review some old results and discuss how they compare to recent data. Following this I discuss some recent work done with Adam Leibovich and Ira Rothstein.Comment: Invited talk: 9th International Symposium on Heavy Flavor Physic

The Borrower\u27s Tale: A History of Poor Debtors in \u3ci\u3eLochner\u3c/i\u3e Era New York City

This study adds to the recent scholarship on Progressivism in practice—fine-grained, place-based studies of reform at the local level—but focuses closely on the relationships among reformers, industry, and the law that an earlier generation of historians studied at the national level and outlined in broad brushstrokes. This study also builds upon the creditor-centered work of historians such as Mark H. Haller and John V. Alviti, but moves beyond their reliance upon distinctions and categories, such as those separating profit making credit providers from philanthropic credit providers, which were less important to borrowers than they have been for historians. In focusing primarily on the lived experience of poor borrowers, this article imports into the study of household credit relationships an approach mapped out by several historians of social welfare policy and institutions, who have attempted to reorient the institution-centered historiography of social welfare to give greater weight to the perspectives of welfare recipients. This study attempts to correct a similar imbalance in the historiography of household credit relationships. The value of viewing the history of credit through the lived experiences of working-class households is not solely in documenting the human dignity and agency of poor borrowers, although this is certainly one of the goals of this study. Rather, by looking at credit relationships from the borrower’s point of view, a number of different institutions, groups, and policies that borrowers experienced as simultaneous and overlapping, but that historians have usually studied separately from one another, are brought into the same analytic frame. Thus, in contrast to prior work, this study treats charitable and for-profit lenders to the poor together as participants in the same market for working-class credit. The debtors’ stories presented here show how impoverished families organized their financial lives, made ends meet, and employed borrowing as a survival strategy

Carbon dioxide as the working fluid in heating and/or cooling systems

Despite vigorous research the use of carbon dioxide in the market is still relatively small. This is due to legislation, and technical difficulties of developing efficient, acceptable carbon dioxide systems
