Lattice-Friendly Gauge Completion of a Composite Higgs with Top Partners
Helene Gertov, Ann E. Nelson, Ashley Perko +1
We give an explicit example of a composite Higgs model with a pseudo-Nambu-Goldstone Higgs in which the top Yukawa coupling is generated via the partial compositeness mechanism. Th…
Dark matter amnesia in out-of-equilibrium scenarios
Joshua Berger, Djuna Croon, Sonia El Hedri +3
Models in which the dark matter is produced at extremely low rates from the annihilation of Standard Model particles in the early Universe allow us to explain the current dark matt…
On the Bispectra of Very Massive Tracers in the Effective Field Theory of Large-Scale Structure
Ethan O. Nadler, Ashley Perko, Leonardo Senatore
The Effective Field Theory of Large-Scale Structure (EFTofLSS) provides a consistent perturbative framework for describing the statistical distribution of cosmological large-scale…
Biased Tracers in Redshift Space in the EFT of Large-Scale Structure
Ashley Perko, Leonardo Senatore, Elise Jennings +1
The Effective Field Theory of Large-Scale Structure (EFTofLSS) provides a novel formalism that is able to accurately predict the clustering of large-scale structure (LSS) in the mi…
Brute-Force Mapmaking with Compact Interferometers: A MITEoR Northern Sky Map from 128 MHz to 175 MHz
H. Zheng, M. Tegmark, J. Dillon +24
We present a new method for interferometric imaging that is ideal for the large fields of view and compact arrays common in 21 cm cosmology. We first demonstrate the method with si…
Analytic Prediction of Baryonic Effects from the EFT of Large Scale Structures
Matthew Lewandowski, Ashley Perko, Leonardo Senatore
The large scale structures of the universe will likely be the next leading source of cosmological information. It is therefore crucial to understand their behavior. The Effective F…
MITEoR: A Scalable Interferometer for Precision 21 cm Cosmology
Haoxuan Zheng, Max Tegmark, Victor Buza +34
We report on the MIT Epoch of Reionization (MITEoR) experiment, a pathfinder low-frequency radio interferometer whose goal is to test technologies that improve the calibration prec…
Leading slow roll corrections to the volume of the universe and the entropy bound
Matthew Lewandowski, Ashley Perko
We make an extension to recent calculations of the probability density ρ(V) for the volume of the universe after inflation. Previous results have been accurate to leading order in…
Mapping our Universe in 3D with MITEoR
Haoxuan Zheng, Max Tegmark, Victor Buza +33
Mapping our universe in 3D by imaging the redshifted 21 cm line from neutral hydrogen has the potential to overtake the cosmic microwave background as our most powerful cosmologica…
The Physical Squeezed Limit: Consistency Relations at Order q^2
Paolo Creminelli, Ashley Perko, Leonardo Senatore +2
In single-field models of inflation the effect of a long mode with momentum q reduces to a diffeomorphism at zeroth and first order in q. This gives the well-known consistency rela…
