“…They search for the axion-induced oscillating magnetic field in the presence of a static magnetic field in a solenoid magnet [40] or an external electric field [41][42][43], using an electronic LC circuit [44,45]. There also exist studies of the searches for axion-induced electric field [46,47]. Nevertheless, to examine the detection of such low-mass ALPs, one needs to first solve the relevant axion Maxwell equations.…”

The Witten effect implies the electromagnetic interactions between axions and magnetic monopoles, and the quantum electromagnetodynamics (QEMD) properly describes interactions of electric charges, magnetic charges and photons. Based on the QEMD, a generic low-energy axion-photon effective field theory was built by introducing two four-potentials (Aμ and Bμ) to describe a photon. More anomalous axion-photon interactions and couplings (gaAA, gaBB and gaAB) arise in contrary to the ordinary axion coupling $$ {g}_{a\gamma \gamma}{a F}^{\mu \nu}{\overset{\sim }{F}}_{\mu \nu} $$ g aγγ aF μν F ~ μν . As a consequence, the conventional axion Maxwell equations are further modified. We properly solve the new axion-modified Maxwell equations and obtain the axion-induced electromagnetic fields given a static electric or magnetic field. It turns out that the dominant couplings gaAB and gaBB can be probed in the presence of external magnetic field and electric field, respectively. The induced oscillating magnetic fields are always suppressed compared with the electric fields for the axions with large Compton wavelengths. This is contrary to the situation in conventional experiments searching for the oscillating magnetic fields induced by sub-μeV axions. Thus, we propose new strategies to measure the new couplings for sub-μeV axion in haloscope experiments.

“…To measure the signal current, one can adopt either a SQUID magnetometer to pick up the generated magnetic field [40], or direct amplifiers to amplify the signal [47]. For the main noise in the signal-to-noise ratio (SNR), we follow the latter method to estimate the thermal noise as…”

We investigate flavor violating four-Fermi Standard Model Effective Field Theory (SMEFT) operators of dimension-six that can be probed via tc$$ \left(\overline{t}c+t\overline{c}\right) $$ t ¯ c + t c ¯ production at the multi-TeV muon collider. We study different FCNC and FCCC processes related to B, Bs, K and D decays and mixings, sensitive to these operators and constrain the corresponding couplings. The tensor operator turns out to be most tightly bound. We perform event simulation of the final state signal from tc production together with the SM background to show that operators after flavor constraint can reach the discovery limit at 10 TeV muon collider. We further adopt the optimal observable technique (OOT) to determine the optimal statistical sensitivity of the Wilson coefficients and compare them with the flavor constraints. We use the limits to predict the observational sensitivities of the rare processes like KL → π0ℓℓ, D0 → μμ, t → cℓℓ.
