Consistent higher derivative gravitational theories with stable de Sitter and anti–de Sitter backgrounds

2017-02-24T10:00:00-05:00

Author(s): Tirthabir Biswas, Alexey S. Koshelev, and Anupam Mazumdar
In this paper we provide the criteria for any generally covariant, parity preserving, and torsion-free theory of gravity to possess a stable de Sitter (dS) or anti–de Sitter (AdS) background. By stability we mean the absence of tachyonic or ghostlike states in the perturbative spectrum that can lead…

Cosmic microwave background limits on accreting primordial black holes

2017-02-24T10:00:00-05:00

Author(s): Yacine Ali-Haïmoud and Marc Kamionkowski

The LIGO observation of black hole merger has revivified interest in the idea whether primordial black holes might comprise some or all of the dark matter. The authors scrutinize the impact of primordial black holes on the CMB, analytically calculating spherical accretion onto black holes. The paper provides stringent constraints on models purporting to connect dark matter to primordial black holes.

Phenomenology of baryon acoustic oscillation evolution from Lagrangian to Eulerian space

2017-02-24T10:00:00-05:00

Author(s): Tobias Baldauf and Vincent Desjacques
The baryon acoustic oscillation (BAO) feature provides an important distance scale for the measurement of the expansion history of the Universe. Theoretical models of the BAO in the distribution of biased tracers of the large-scale structure usually rely on an initially linear BAO. With aid of N-bod…

Using Dirac’s method for the quantization of constrained systems QED is canonically quantized in the front form in a gauge which is the light-front analog of the Weyl gauge. From the obtained vacuum wave functional the spatial Wilson loop is calculated. The result known from the canonical instant-fo…

Drell-Yan hadron tensor: Contour gauge and gluon propagator

Author(s): I. V. Anikin, I. O. Cherednikov, and O. V. Teryaev
We consider the gauge invariant Drell-Yan hadron tensor which includes the standard and nonstandard diagram contributions. The nonstandard diagram contribution appeared owing to the complexity of the twist three B^{V}(x_{1},x_{2})-function where the gluon pole manifests. We use the contour gauge con…

We propose measurements of weighted differences of the angular observables in the rare decays B→K^{*}ℓ^{+}ℓ^{−}. The proposed observables are very sensitive to the difference between the Wilson coefficients C_{9}^{(e)} and C_{9}^{(μ)} for decays into electrons and muons, respectively. At the same ti…

A unified theory of the non-Abelian gauge interactions with gravity in the framework of a discretized Kaluza-Klein theory is constructed with a modified Dirac operator and wedge product.

Author(s): H. F. Gruetjen, J. R. Fergusson, M. Liguori, and E. P. S. Shellard
The direct evaluation of manifestly optimal, cut-sky cosmic microwave background (CMB) power spectrum and bispectrum estimators is numerically very costly, due to the presence of inverse-covariance filtering operations. This justifies the investigation of alternative approaches. In this work, we mos…

We investigate whether transition radiation from a particle shower crossing the interface between Earth and air and induced by an Earth-skimming neutrino can explain the upward event announced recently by the ANITA Collaboration. While the properties of the observed signal can in principle be explai…

Off-shell dark matter: A cosmological relic of quantum gravity

2017-02-17T10:00:00-05:00

Author(s): Mehdi Saravani and Niayesh Afshordi
We study a novel proposal for the origin of cosmological cold dark matter (CDM) which is rooted in the quantum nature of spacetime. In this model, off-shell modes of quantum fields can exist in asymptotic states as a result of spacetime nonlocality (expected in generic theories of quantum gravity) a…
