Effective Field Theory for Inflation
Steven Weinberg
The methods of effective field theory are used to study generic theories of inflation with a single inflaton field. For scalar modes, the leading corrections to the corr…
Tensor Microwave Background Fluctuations for Large Multipole Order
Raphael Flauger, Steven Weinberg
We present approximate formulas for the tensor BB, EE, TT, and TE multipole coefficients for large multipole order l. The error in using the approximate formula for the BB multipol…
The Cosmological Constant Problems (Talk given at Dark Matter 2000, February, 2000)
Steven Weinberg
The old cosmological constant problem is to understand why the vacuum energy is so small; the new problem is to understand why it is comparable to the present mass density. Several…
What is Quantum Field Theory, and What Did We Think It Is?
Steven Weinberg
This is a talk presented at the conference ``Historical and Philosophical Reflections on the Foundations of Quantum Field Theory,'' at Boston University, March 1996. It will be pub…
