#### An analysis of nonoblique corrections to the Zb¯b vertex

(1994)

We present a model–independent analysis of the Zb¯b vertex, with the aim of constraining contributions of new physics to the left- and right–handed couplings of the b. We find that the left–handed coupling of the b is quite ...

#### Precision Tests of Electroweak Physics

We review the current status of precision electroweak measurements and the constraints they impose on new physics. We perform a model independent analysis using the STU-formalism of Ref. 1, and then discuss how the Z-pole ...

#### Exact solution of the harmonic oscillator in arbitrary dimensions with minimal length uncertainty relations

(American Physical Society, 2002-06-15)

We determine the energy eigenvalues and eigenfunctions of the harmonic oscillator where the coordinates and momenta are assumed to obey the modified commutation relations [(x) over cap (i),(p) over cap (j)]=i (h) over ...

#### Effect of the minimal length uncertainty relation on the density of states and the cosmological constant problem

(American Physical Society, 2002-06-15)

We investigate the effect of the minimal length uncertainty relation, motivated by perturbative string theory, on the density of states in momentum space. The relation is implemented through the modified commutation relation ...

#### Hydrogen-atom spectrum under a minimal-length hypothesis

(Amer Physical Soc, 2005-07-01)

#### Short distance versus long distance physics: The classical limit of the minimal length uncertainty relation

(American Physical Society, 2002-07-15)

We continue our investigation of the phenomenological implications of the "deformed" commutation relations [(x) over cap (i),(p) over cap (j)]=i (h) over bar[(1+beta(p) over cap (2))delta(ij)+beta'(p) over cap (i)(p) over ...

#### Quantum Gravity, Dynamical Energy-Momentum Space and Vacuum Energy

(World Scientific Publ Co Pte Ltd, 2010-11-01)

#### Classical Implications of the Minimal Length Uncertainty Relation

We study the phenomenological implications of the classical limit of the "stringy" commutation relations [x_i,p_j]=i hbar[(1+beta p^2) delta_{ij} + beta' p_i p_j]. In particular, we investigate the "deformation" of Kepler's ...

#### Hydrogen-atom spectrum under a minimal-length hypothesis

(American Physical Society, 2005-07)

The energy spectrum of the Coulomb potential with minimal length commutation relations [X-i, P-j] = ih{delta ij(1 + beta P-2) + beta PiPj} is determined both numerically and perturbatively for arbitrary values of beta'/beta ...
