Asymptotically Safe Dark Matter
Francesco Sannino, Ian M. Shoemaker
We introduce a new paradigm for dark matter (DM) interactions in which the interaction strength is asymptotically safe. In models of this type, the coupling strength is small at lo…
Elementary Goldstone Higgs Boson and Dark Matter
Tommi Alanne, Helene Gertov, Francesco Sannino +1
We investigate a perturbative extension of the Standard Model featuring elementary pseudo-Goldstone Higgs and dark matter particles. These are two of the five Goldstone bosons para…
Inflationary dynamics of kinetically-coupled gauge fields
Ricardo Z. Ferreira, Jonathan Ganc
We investigate the inflationary dynamics of two kinetically-coupled massless gauge fields with time-varying kinetic-term coefficients. Ensuring that the system does not have…
Universal Constraints on Axions from Inflation
Ricardo Z. Ferreira, Martin S. Sloth
We consider the presence of an axion like particle, , with a generic violating axial coupling of the form , where is the gauge field streng…
How many nucleosynthesis processes exist at low metallicity?
C. J. Hansen, F. Montes, A. Arcones
Abundances of low-metallicity stars offer a unique opportunity to understand the contribution and conditions of the different processes that synthesize heavy elements. Many old, me…
Covariant constraints for generic massive gravity and analysis of its characteristics
S. Deser, M. Sandora, A. Waldron +1
We perform a covariant constraint analysis of massive gravity valid for its entire parameter space, demonstrating that the model generically propagates five degrees of freedom; thi…
Removing the gauge parameter dependence of the effective potential by a field redefinition
N. K. Nielsen
The gauge parameter dependence of the effective potential is determined by partial differential equations involving also the Higgs boson field expectation value. Solving these equa…
Effect of asphericity in caustic mass estimates of galaxy clusters
Jacob Svensmark, Radoslaw Wojtak, Steen H. Hansen
The caustic technique for measuring mass profiles of galaxy clusters relies on the assumption of spherical symmetry. When applied to aspherical galaxy clusters, the method yields m…
Probing correlations of early magnetic fields using mu-distortion
Jonathan Ganc, Martin S. Sloth
The damping of a non-uniform magnetic field between the redshifts of about and injects energy into the photon-baryon plasma and causes the CMB to deviate from a perfe…
Search for dark matter in events with a Z boson and missing transverse momentum in pp collisions at =8 TeV with the ATLAS detector
ATLAS Collaboration
A search is presented for production of dark matter particles recoiling against a leptonically decaying Z boson in 20.3 fb of pp collisions at =8 TeV with the ATLA…
The Gravitational Wave Background and Higgs False Vacuum Inflation
Isabella Masina
For a narrow band of values of the top quark and Higgs boson masses, the Standard Model Higgs potential develops a shallow local minimum at energies of about GeV, where p…
Renormalization-Group Flows and Fixed Points in Yukawa Theories
Esben Mølgaard, Robert Shrock
We study renormalization-group flows in Yukawa theories with massless fermions, including determination of fixed points and curves that separate regions of different flow behavior.…
Confinement, Phase Transitions and non-Locality in the Entanglement Entropy
Uri Kol, Carlos Nunez, Daniel Schofield +2
In this paper we study the conjectural relation between confinement in a quantum field theory and the presence of a phase transition in its corresponding entanglement entropy. We d…
Chaotic inflation with curvaton induced running
Martin S. Sloth
While dust contamination now appears as a likely explanation of the apparent tension between the recent BICEP2 data and the Planck data, we will here explore the consequences of a…
Constraining new coloured matter from the ratio of 3- to 2-jets cross sections at the LHC
Diego Becciolini, Marc Gillioz, Marco Nardecchia +2
The Large Hadron Collider experiments are probing the evolution of the strong coupling up to the TeV scale. We show how the ratio of 3- to 2-jets cross sections is affected b…
Inflationary Magnetogenesis without the Strong Coupling Problem II: Constraints from CMB anisotropies and B-modes
Ricardo J. Z. Ferreira, Rajeev Kumar Jain, Martin S. Sloth
Recent observational claims of magnetic fields stronger than G in the extragalactic medium motivate a new look for their origin in the inflationary magnetogenesis models…
Primordial tensor modes from quantum corrected inflation
Jakob Joergensen, Francesco Sannino, Ole Svendsen
We analyze quantum corrections on the naive -Inflation. These typically lead to an inflaton potential which carries a non-integer power of the field. We consider both minimal…
X-ray Lines from Dark Matter: The Good, The Bad, and The Unlikely
Mads Frandsen, Francesco Sannino, Ian M. Shoemaker +1
We consider three classes of dark matter (DM) models to account for the recently observed 3.5 keV line: metastable excited state DM, annihilating DM, and decaying DM. We study two…
New Type IIB Backgrounds and Aspects of Their Field Theory Duals
Elena Caceres, Niall T. Macpherson, Carlos Nunez
In this paper we study aspects of geometries in Type IIA and Type IIB String theory and elaborate on their field theory dual pairs. The backgrounds are associated with reductions t…
Helioseismology with long range dark matter-baryon interactions
Ilídio Lopes, Paolo Panci, Joseph Silk
Assuming the existence of a primordial asymmetry in the dark sector, we study how DM-baryon long-range interactions, induced by the kinetic mixing of a new gauge boson and t…
