Looking at the axionic dark sector with ANITA by I. Esteban, J. Lopez-Pavon, I. Martinez-Soler, J. Salvado

“…Furthermore, we propose that these pulses can be resonantly produced in the ionosphere via axion–photon conversion. This naturally explains the direction and polarization of the events and avoids other experimental bounds.…”

On the fermionic couplings of axionic dark matter by Christopher Smith

“…Abstract In the non-relativistic limit, two types of dark matter axion interactions with fermions are thought to dominate: one is induced by the spatial gradient of the axion field and called the axion wind, and the other by the time-derivative of the axion field, generating axioelectric effects. …”

Is the bump significant? An axion-search example by Frederik Beaujean, Allen Caldwell, Olaf Reimann

“…The method is verified for benchmark cases and successfully applied to real data from an axion search. C++ code that implements our method is available at https://github.com/fredRos/runs.…”

Universal axion backreaction in flux compactifications by Thomas W. Grimm, Chongchuo Li

“…Abstract We study the backreaction effect of a large axion field excursion on the saxion partner residing in the same N $$ \mathcal{N} $$ = 1 multiplet. …”

Dynamics of superconformal axion: Quality and scalegenesis by Shota Nakagawa, Yuichiro Nakai, Masaki Yamada, Yufei Zhang

“…We explore a dynamical mechanism to realize the emergence of a global U(1)PQ symmetry and its spontaneous breaking at an intermediate scale for an axion solution to the strong CP problem. Such a dynamics is provided by a new supersymmetric QCD near the middle of conformal window that couples to fields spontaneously breaking the U(1)PQ symmetry. …”

Erratum to: The minimal flavour violating axion by F. Arias-Aragón, L. Merlo

“…In this erratum we clarify that in contrast to the statements made in the article the bounds on the axion coupling to two W ’s and to two Z ’s obtained from mono-W and mono-Z searches…”

Non-invertible Gauss law and axions by Yichul Choi, Ho Tat Lam, Shu-Heng Shao

“…Abstract In axion-Maxwell theory at the minimal axion-photon coupling, we find non-invertible 0- and 1-form global symmetries arising from the naive shift and center symmetries. …”

A fundamental QCD axion model by Alberto Salvio

“…We construct and study a fundamental field theory of the QCD axion: all couplings flow to zero in the infinite-energy limit realizing the totally asymptotically free (TAF) scenario. …”

Holographic superfluid with gauge–axion coupling by Yan Liu, Xi-Jing Wang, Jian-Pin Wu, Xin Zhang

“…Abstract We have constructed a holographic superfluid with gauge–axion coupling. Depending on whether the coupling is positive or negative, the system displays metallic or insulating behavior in its normal state. …”

New axion searches at flavor factories by Xabier Cid Vidal, Alberto Mariotti, Diego Redigolo, Filippo Sala, Kohsaku Tobioka

“…We estimate that a future LHCb dedicated search would test an axion decay constant of O(TeV) for axion masses in the few-to-tens of GeV, being fully complementary to the low mass ATLAS and CMS searches. …”

On self-similar axion-dilaton configurations by Riccardo Antonelli, Ehsan Hatefi

“…Abstract We explore self-similar collapse solutions to the Einstein-axion-dilaton system in arbitrary spacetime dimensions, which are invariant under spacetime dilation combined with internal SL(2, ℝ) transformations. …”

Gravitational waves from supercool axions by Luigi Delle Rose, Giuliano Panico, Michele Redi, Andrea Tesi

“…Abstract We study the dynamics of the Peccei-Quinn (PQ) phase transition for the QCD axion. In weakly coupled models the transition is typically second order except in the region of parameters where the PQ symmetry is broken through the Coleman-Weinberg mechanism. …”

Holographic phonons by gauge-axion coupling by Xi-Jing Wang, Wei-Jia Li

“…Abstract In this paper, we show that a simple generalization of the holographic axion model can realize spontaneous breaking of translational symmetry by considering a special gauge-axion higher derivative term. …”

Natural axion model from flavour by Salvador Centelles Chuliá, Christian Döring, Werner Rodejohann, Ulises J. Saldaña-Salazar

“…We work in the context of a four-Higgs-doublet model which explains all quark and charged fermion masses with natural, i.e. order 1, Yukawa couplings. Moreover, the axion of the model constitutes a viable dark matter candidate and neutrino masses are incorporated via the standard type-I seesaw mechanism. …”

Flux flattening in axion monodromy inflation by Aitor Landete, Fernando Marchesano, Gary Shiu, Gianluca Zoccarato

“…Abstract String theory models of axion monodromy inflation exhibit scalar potentials which are quadratic for small values of the inflaton field and evolve to a more complicated function for large field values. …”
