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
