“…Searches for such KK axions have been conducted in the context of the so-called axion-like particles. In the present model, the KK axions are expected to be at around the TeV scale so that they could be a target of the LHC and future collider experiments [60][61][62][63][64][65][66]. At colliders with sufficiently high energies, the KK axions are resonantly produced through e.g.…”

We explore a new framework that furnishes a mechanism to simultaneously address the electroweak naturalness problem and the axion high quality problem. The framework is based on a doubly composite dynamics where the second confinement takes place after the CFT encounters the first confinement and the theory flows into another conformal fixed point. For a calculable example, we present a holographic dual description of the 4D model via a warped extra dimension model with three 3-branes. While the hierarchy problem is taken cared of by the localization of the Higgs fields on the TeV brane just as in the original Randall-Sundrum model, the Peccei-Quinn (PQ) symmetry is realized as a gauge symmetry in the bulk of the extra dimension to solve the axion quality problem. We introduce a 5D scalar field whose potential at the intermediate brane drives spontaneous breaking of the PQ symmetry. Then, the PQ breaking scale is given by the scale of the intermediate brane and is naturally small compared to the Planck scale. The axion bulk profile is significantly suppressed around the UV brane, which protects the axion from gravitational violations of the PQ symmetry on the UV brane. Our model genuinely predicts the existence of the Kaluza-Klein excitations of the QCD axion at around the TeV scale and relatively light extra Higgs bosons.

“…[20], the ALP-strahlung processes have also been studied at the CLIC, but the author assumes C WW = 0, considering γZa coupling, which is opposite to our work. There are previous works about the ALP single production induced by two-photon fusion in future electron-positron colliders [34][35][36]. Thus, in this paper, we only consider the production of ALP via W + W − fusion process e + e − → ν e ν e a with a subsequently decaying to photon pairs (see Fig.…”

“…The constraints on a wide range of the ALP parameter space are obtained using the available data, such as the LEP, Tevatron and LHC data, the future prospects of discovering ALPs at running or future collider experiments are studied. For instance, searches for ALPs via photon fusion are investigated at the LHC and e + e − colliders [30][31][32][33][34][35][36][37][38]. The capabilities of these colliders to probe the ALP parame-ter space are discussed and the expected bounds on the ALPphoton coupling for a wide range of masses are obtained.…”

One kind of particularly interesting pseudoscalar particles, called axion-like particles (ALPs), have rich physical phenomenology at high-and low-energy collider experiments. After discussing most of single production channels of ALP at electron-positron colliders, we investigate the possibility of detecting this kind of new particles through the W + W − fusion process e + e − → ν e ν e a (→ γγ) at the CLIC. The 3σ and 5σ bounds on the ALP parameter space at the three energy stages of the CLIC are obtained. We find that the bounds given by the CLIC are complementary to the existing experiments exclusion regions.

Our study of theoretical uncertainties for the four bosons processes at one-loop level including the case of the transverse polarization is presented. The calculations are based on helicity amplitudes approach for 4-boson SM interactions through a fermion and boson loops. The computation takes into account nonzero mass of loop particles. The obtained predictions are equally suitable for a wide range of energies and for arbitrary, including extreme, regions of the phase volume. Uncertainty estimates are received using the new Monte-Carlo tool SANCphot for γγ collision simulation with final states γγ, γZ, ZZ adapted for polarized γ beams.
