Color Octet Scalar Production at the LHC

New physics at the weak scale that can couple to quarks typically gives rise to unacceptably large flavor changing neutral currents. An attractive way to avoid this problem is to impose the principal of minimal flavor violation (MFV). Recently it was noted that in MFV only scalars with the same gauge quantum numbers as the standard model Higgs doublet or color octet scalars with the same weak quantum numbers as the Higgs doublet can couple to quarks. In this paper we compute the one-loop rate for production of a single color octet scalar through gluon fusion at the LHC, which can become greater than the tree level pair production rate for octet scalar masses around a TeV. We also calculate the precision electroweak constraint from Z decays to a b and anti-b quark; this constraint on color octet mass and Yukawa coupling affects the allowed range for single octet scalar production through gluon fusion.Comment: 15 pages, 5 figure

Reverse Triangle Inequalities for Riesz Potentials and Connections with Polarization

We study reverse triangle inequalities for Riesz potentials and their connection with polarization. This work generalizes inequalities for sup norms of products of polynomials, and reverse triangle inequalities for logarithmic potentials. The main tool used in the proofs is the representation for a power of the farthest distance function as a Riesz potential of a unit Borel measure

Classical stability of a homogeneous, anisotropic inflating space-time

We study the classical stability of an anisotropic space-time seeded by a spacelike, fixed norm, dynamical vector field in a vacuum-energy-dominated inflationary era. It serves as a model for breaking isotropy during the inflationary era. We find that, for a range of parameters, the linear differential equations for small perturbations about the background do not have a growing mode. We also examine the energy of fluctuations about this background in flat-space. If the kinetic terms for the vector field do not take the form of a field strength tensor squared then there is a negative energy mode and the background is unstable. For the case where the kinetic term is of the form of a field strength tensor squared we show that perturbations about the background have positive energy at lowest order.Comment: 12 pages, no figures; references added, content in section V revised and some clarification made in text; minor typos corrected, v4 closely resembles version published in Phys. Rev. D; in v5 - incorrect argument in section V removed and one reference adde

Cubulating hyperbolic free-by-cyclic groups: the general case

Let $\Phi:F\rightarrow F$ be an automorphism of the finite-rank free group $F$. Suppose that $G=F\rtimes_\Phi\mathbb Z$ is word-hyperbolic. Then $G$ acts freely and cocompactly on a CAT(0) cube complex.Comment: 36 pages, 11 figures. Version 2 contains minor corrections. Accepted to GAF

Statistical Properties of Interacting Bose Gases in Quasi-2D Harmonic Traps

The analytical probability distribution of the quasi-2D (and purely 2D) ideal and interacting Bose gas are investigated by using a canonical ensemble approach. Using the analytical probability distribution of the condensate, the statistical properties such as the mean occupation number and particle number fluctuations of the condensate are calculated. Researches show that there is a continuous crossover of the statistical properties from a quasi-2D to a purely 2D ideal or interacting gases. Different from the case of a 3D Bose gas, the interaction between atoms changes in a deep way the nature of the particle number fluctuations.Comment: RevTex, 10pages, 4 figures, E-mail: [email protected]

Aesthetic Awareness and Spectacle: Communicated Images of Novi Sad, the Exit Festival and the Event Venue Petrovaradin Fortress

More research and discussion is needed to understand how destination image and awareness links to aesthetic portrayals. Representations of image, awareness, and aesthetics are embedded in textual content, and the narratives portrayed offer valuable meaning that is open to interpretation. Newspaper articles and websites play a crucial role in creating and presenting new images of places to international audiences. While image is certain, what is often overlooked in textual sources are discussions addressing the importance of aesthetics, which also link to destination image and awareness. The city of Novi Sad, Serbia represents a unique case given the location of the city's popular music event, the Exit Festival, which attracts youths from across the former Yugoslavia, Europe and the world and has contributed to a new image of Serbia. Moreover, the event's unique setting, held in the Petrovaradin Fortress on the banks of the Danube River overlooking Novi Sad, is described in relation to historical/cultural ambiance, and aesthetic attributes. Sources analyzed stressed the beauty of Novi Sad and the festival venue, but mere notions of spectacle could not be ignored. Discussions of image, awareness, and aesthetic dimensions presented in newspaper content and websites are analyzed in this article to understand how the festival textual content challenges us to re-create place meanings of Serbia.
