We find and classify the simplest ${\cal N}=2$ SUSY multiplets on AdS$_4$ which contain partially massless fields. We do this by studying representations of the ${\cal N}=2$, $d=3$ superconformal algebra
Constraints on Axions from Cosmic Distance Measurements. (arXiv:2011.05993v1 [hep-ph])
Axion couplings to photons could induce photon-axion conversion in the presence of magnetic fields in the Universe. The conversion could impact various cosmic distance measurements such as luminosity distances to
Primordial black hole dark matter in dilaton-extended two-field Starobinsky inflation. (arXiv:2011.05999v1 [hep-th])
We investigate the production of primordial black holes and their contribution to the presently observed dark matter in a dilaton two-field extension of Starobinsky’s quadratic $f(R)$ model of inflation. The
Heavy Axion Opportunities at the DUNE Near Detector. (arXiv:2011.05995v1 [hep-ph])
While the QCD axion is often considered to be necessarily light ($\lesssim$ eV), recent work has opened a viable and interesting parameter space for heavy axions, which solve both the
The bi-conical vector model at $1/N$. (arXiv:2011.06003v1 [hep-th])
We study finite $N$ aspects of the $O(m)\times O(N-m)$ vector model with quartic interactions in general $2\leq d \leq 6$ spacetime dimensions. This model has recently been shown to display
Subleading BMS Charges and The Lorentz Group. (arXiv:2011.06008v1 [hep-th])
The extended BMS group includes supertranslation, dual supertranslation and Lorentz transformations. The generators of these symmetries can be classified according to their parity into “electric” and “magnetic” types. Using a
Constraints on ultralight scalar bosons within black hole spin measurements from LIGO-Virgo’s GWTC-2. (arXiv:2011.06010v1 [gr-qc])
Clouds of ultralight bosons – such as axions – can form around a rapidly spinning black hole, if the black hole radius is comparable to the bosons’ wavelength. The cloud
Effective field theory analysis of composite higgsino-like and wino-like thermal relic dark matter. (arXiv:2011.06025v1 [hep-ph])
We study the effective field theory (including operators up to dimension five) of models in which dark matter is composite, consisting of either an electroweak doublet Dirac fermion (`higgsino-like dark
Signatures of global symmetry violation in relative entropies and replica wormholes. (arXiv:2011.06005v1 [hep-th])
It is widely believed that exact global symmetries do not exist in theories that admit quantum black holes. Here we propose a way to quantify the degree of global symmetry
Three-Body Baryonic $ \bar{B}^{0}\rightarrow\Lambda^+_c \bar{p} \pi^0$ Decay. (arXiv:2011.06068v1 [hep-ph])
We study the three-body baryonic decay $ \bar{B}^{0}\rightarrow\Lambda^+_c \bar{p} \pi^0$ based on the factorization approach. The most important Feynman diagrams for this decay mode are factorizable and non-factorizable contributions, so
