Universal Non-perturbative Functions for SIDIS and Drell-Yan Processes

We update the well-known BLNY fit to the low transverse momentum Drell-Yan lepton pair productions in hadronic collisions, by considering the constraints from the semi-inclusive hadron production in deep inelastic scattering (SIDIS) from HERMES and COMPASS experiments. We follow the Collins-Soper-Sterman (CSS) formalism with the b_*-prescription. A universal non-perturbative form factor associated with the transverse momentum dependent quark distributions is found in the analysis with a new functional form different from that of BLNY. This releases the tension between the BLNY fit to the Drell-Yan data with the SIDIS data from HERMES/COMPASS in the CSS resummation formalism.Comment: 19 pages, 11 figures; updated the fit with running effects of \alpha_{s}, \alpha_{em}, N_f; conclusion remains; more discussions on the result

Resummation of High Order Corrections in Higgs Boson Plus Jet Production at the LHC

We study the effect of multiple parton radiation to Higgs boson plus jet production at the LHC, by applying the transverse momentum dependent (TMD) factorization formalism to resum large logarithmic contributions to all orders in the expansion of the strong interaction coupling. We show that the appropriate resummation scale should be the jet transverse momentum, rather than the partonic center of mass energy which has been normally used in the TMD resummation formalism. Furthermore, the transverse momentum distribution of the Higgs boson, particularly near the lower cut-off applied on the jet transverse momentum, can only be reliably predicted by the resummation calculation which is free of the so-called Sudakov-shoulder singularity problem, present in fixed-order calculations.Comment: 7 pages, 4 figure

Pittsburgh\u27s Response to Deindustrialization: Renaissance, Renewal and Recovery, 1946-1999

Pittsburgh was able to gradually ease its transition into a post-industrial economy in the second half of the twentieth century because of an elite-driven planning movement known as the Pittsburgh Renaissance. The Renaissance first addressed the physical failings of the city and sought state legislation that would support further urban redevelopment immediately following World War II. While the physical improvements were underway, Renaissance organizers began working with the University of Pittsburgh to upgrade Pitt\u27s educational and recreational facilities so that it would become an engine for the city\u27s future economic growth. City support for improved facilities, especially those pertaining to the growing medical center and scientific research programs, laid the foundation for the city\u27s post-industrial economy. Evolving plans for a new municipal amphitheater also began in the mid-1940s, but merged with the federal urban renewal program in the mid-1950s. The intention was to turn Pittsburgh into a business tourism destination that would highlight the city\u27s cultural assets with an adjacent Center for the Arts, but the finished facility failed to meet the expectations planners set for it and constituted a transformative experience for the Renaissance movement. When Renaissance planning resumed in the late 1970s, it returned without centralized control, but it shared the goals of promoting Downtown Pittsburgh as a business center, diversifying the city\u27s economy away from steel, and emphasizing the city\u27s cultural institutions. As Renaissance continued through the next two decades, these core values continued to motivate projects and link it to past accomplishments solidifying the importance of planning to the city\u27s operations. By responding to the threat of capital flight in the 1940s, the Renaissance created a movement that could outlast any individual participants, suspend and resume operations as needed, and adapt to meet different crises that emerged over time

HD 4915: A Maunder Minimum Candidate

We study the magnetic activity cycle of HD 4915 using the \ion{Ca}{2} H \& K emission line strengths measured by Keck I/HIRES spectrograph. The star has been observed as a part of California Planet Search Program from 2006 to present. We note decreasing amplitude in the magnetic activity cycle, a pattern suggesting the star's entry into a Magnetic Grand Minimum (MGM) state, reminiscent of the Sun's Maunder and Dalton Minima. We recommend further monitoring of the star to confirm the grand minimum nature of the dynamo, which would provide insight into the state of the Sun's chromosphere and the global magnetic field during its grand minima. We also recommend continued observations of H \& K emission lines, and ground or space based photometric observations to estimate the sunspot coverage.Comment: To be submitted to AAS Journals; comments welcom

Information-disturbance tradeoff in estimating a maximally entangled state

We derive the amount of information retrieved by a quantum measurement in estimating an unknown maximally entangled state, along with the pertaining disturbance on the state itself. The optimal tradeoff between information and disturbance is obtained, and a corresponding optimal measurement is provided.Comment: 4 pages. Accepted for publication on Physical Review Letter

The incorporation of matter into characteristic numerical relativity

A code that implements Einstein equations in the characteristic formulation in 3D has been developed and thoroughly tested for the vacuum case. Here, we describe how to incorporate matter, in the form of a perfect fluid, into the code. The extended code has been written and validated in a number of cases. It is stable and capable of contributing towards an understanding of a number of problems in black hole astrophysics.Comment: 15 pages + 4 (eps) figure
