Heavy Black Hole Effective Theory
Poul H. Damgaard, Kays Haddad, Andreas Helset
We formulate an effective field theory describing large mass scalars and fermions minimally coupled to gravity. The operators of this effective field theory are organized in powers…
The Angular Power Spectrum of Heavy Ion Collisions
Meera Machado, Poul Henrik Damgaard, Jens Jørgen Gaardhøje +1
Particles produced in heavy ion collisions carry information about anisotropies present already in the early state of the system and play a crucial role in understanding the Quark…
Effective Field Theory and Electroweak Baryogenesis in the Singlet-Extended Standard Model
P. H. Damgaard, A. Haarr, D. O'Connell +1
Electroweak baryogenesis is a simple and attractive candidate mechanism for generating the observed baryon asymmetry in the Universe. Its viability is sometimes investigated in ter…
Constraints on New Physics from Baryogenesis and Large Hadron Collider Data
Poul H. Damgaard, Donal O'Connell, Troels C. Petersen +1
We demonstrate the power of constraining theories of new physics by insisting that they lead to electroweak baryogenesis, while agreeing with current data from the Large Hadron Col…
Unusual identities for QCD at tree-level
N. E. J. Bjerrum-Bohr, Poul H. Damgaard, Bo Feng +1
We discuss a set of recently discovered quadratic relations between gauge theory amplitudes. Such relations give additional structural simplifications for amplitudes in QCD. Remark…
The Dirac Operator Spectrum and Effective Field Theory
P. H. Damgaard
When chiral symmetry is spontaneously broken, the low-energy part of the Dirac operator spectrum can be computed analytically in the chiral limit. The tool is effective field theor…
Collective Fields for QCD
P. H. Damgaard, H. B. Nielsen, R. Sollacher
A gauge-symmetric approach to effective Lagrangians is described with special emphasis on derivations of effective low-energy Lagrangians from QCD. The examples we discuss are base…
