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
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
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
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
Making the Universe at 20 MeV. (arXiv:2011.06115v1 [hep-ph])
We present a testable mechanism of low-scale baryogenesis and dark matter production in which neither baryon nor lepton number are violated. Charged $D$ mesons are produced out-of-equilibrium at tens of
Structure of the nucleon at leading and subleading twist in the covariant parton model. (arXiv:2011.06203v1 [hep-ph])
The covariant parton model is generalized to describe quark correlators in a systematic way. Previous results are reproduced for the T-even leading-twist transverse momentum dependent parton distribution functions (TMDs), and
Vacuum Fluctuation Approach to study Neutrino Interactions. (arXiv:2011.06251v1 [hep-ph])
Neutrino oscillation parameters can be understood in a better way by building a more complete picture of neutrino interactions. This poses a series of important theoretical and experimental challenges, given
Softly shifting away from dark matter direct detection. (arXiv:2011.06264v1 [hep-ph])
We propose soft breaking mechanism for dark matter (DM) shift symmetry in a class of composite dark matter models, where both DM and the Higgs boson arise as pseudo Nambu-Goldstone
