Big-bang Nucleosynthesis Predictions for Precision Cosmology
The determination of the primeval deuterium abundance has opened a precision era in big-bang nucleosynthesis (BBN), making accurate predictions more important than ever before. We present in analytic form new, more precise predictions for the light-element abundances and their error matrix. Using our predictions and the primeval deuterium abundance we infer a baryon density of Bh = 0:020 0:002 ...
متن کاملPrecision of inflationary predictions and recent CMB anisotropy data
Inflationary predictions of the cosmic microwave background anisotropy are often based on the slow-roll approximation. We study the precision of these predictions and compare them with the recent data from BOOMERanG and MAXIMA-1.
متن کاملTowards High-Precision Predictions for the MSSM Higgs Sector
The status of the evaluation of the MSSM Higgs sector is reviewed. The phenomenological impact of recently obtained corrections is discussed. In particular it is shown that the upper bound on mh within the MSSM is shifted upwards. Consequently, lower limits on tan β obtained by confronting the upper bound as function of tanβ with the lower bound on mh from Higgs searches are significantly weake...
متن کاملPrecision predictions for Z ′ production at the LHC
We present precision calculations of the transverse-momentum spectrum, the invariant-mass distribution and the total cross section for Z′ production at hadron colliders. We implement joint resummation at the next-to-leading logarithmic accuracy and consistently match the obtained result with the pure perturbative result at the first order in the strong coupling constant. We confront our numeric...
متن کاملThe Uncertainty in Newton’s Constant and Precision Predictions of the Primordial Helium Abundance
[1]1̇1 document The Uncertainty in Newton’s Constant and Precision Predictions of the Primordial Helium Abundance Robert J. Scherrer Department of Physics and Astronomy, Vanderbilt University, Nashville, TN 37235 abstract The current uncertainty in Newton’s constant, GN , is of the order of 0.15%. For values of the baryon to photon ratio consistent with both cosmic microwave background observati...
