To account for the dark-matter content in our Universe, postinflationary scenarios predict QCD axion a mass range $(10--{10}^{3})\text{ }\text{ }\ensuremath{\mu}\mathrm{eV}$. Searches with haloscope experiments this require monitoring of resonant cavity modes frequency above 5 GHz, where several experimental limitations occur due to linear amplifiers, small volumes, and low quality factors copper cavities. In paper, we deal last issue, presenting result search galactic axions using based on...
A haloscope of the QUAX--$a\gamma$ experiment composed an oxygen-free high thermal conductivity-Cu cavity inside 8.1 T magnet and cooled to $\sim200$ mK is put in operation for search galactic axion with mass $m_a\simeq43~\mu\text{eV}$. The power emitted by resonant amplified a Josephson parametric amplifier whose noise fluctuations are at standard quantum limit. With data collected about 1 h frequency $\nu_c=10.40176$ GHz, reaches sensitivity necessary detection QCD-axion, setting $90\%$...
We have measured the cross section of radiative process e+e- -> pi+pi-gamma with KLOE detector at Frascati phi-factory DAPHNE, from events taken a CM energy W=1 GeV. Initial state radiation allows us to obtain for pi+pi-, pion form factor |F_pi|^2 and dipion contribution muon magnetic moment anomaly, Delta a_mu^{pipi} = (478.5+-2.0_{stat}+-5.0_{syst}+-4.5_{th}) x 10^{-10} in range 0.1 < M_{pipi}^2 0.85 GeV^2, where theoretical error includes SU(3) ChPT estimate uncertainty on photon final...
A ferromagnetic axion haloscope searches for dark matter in the form of axions by exploiting their interaction with electronic spins. It is composed an axion-to-electromagnetic field transducer coupled to a sensitive rf detector. The former photon-magnon hybrid system, and latter based on quantum-limited Josephson parametric amplifier. system consists ten 2.1 mm diameter yttrium iron garnet spheres single microwave cavity mode means static magnetic field. Our setup most spin magnetometer...
A haloscope of the QUAX--$a\ensuremath{\gamma}$ experiment, composed an high-$Q$ resonant cavity immersed in a 8 T magnet and cooled to $\ensuremath{\sim}4.5\text{ }\text{ }\mathrm{K}$ is operated search for galactic axions with mass ${m}_{a}\ensuremath{\simeq}42.8\text{ }\ensuremath{\mu}\mathrm{eV}$, not accessible other running experiments. The design hollow dielectric cylinders concentrically inserted OFHC Cu cavity, allowed us maintain loaded quality-factor...
Axions, originally proposed to solve the strong CP problem of quantum chromodynamics, emerge now as leading candidates WISP dark matter. The rich phenomenology associated light and stable QCD axion can be described an effective magnetic field that experimentally investigated. For QUAX experiment, matter axions are searched by means their resonant interactions with electronic spins in a magnetized sample. In principle, axion-induced magnetization changes detected embedding sample rf cavity...
A traveling wave parametric amplifier has been integrated in the haloscope of QUAX experiment. search for dark matter axions performed with a high-$Q$ dielectric cavity immersed an 8 T magnetic field and read by detection chain having system noise temperature about 2.1 K at frequency 10.353 GHz. Scanning conducted varying using sapphire rods into cavity. At multiple operating frequencies, sensitivity instrument was level viable axion models.
High-frequency gravitational waves (HFGWs) are predicted in various exotic scenarios involving both cosmological and astrophysical sources. These elusive signals have recently sparked the interest of a diverse community researchers, due to possibility HFGW detection laboratory through graviton-photon conversion strong magnetic fields. Notable examples include redesign resonant cavities currently under development detect cosmic axion. In this work, we derive sensitivities some existing...
Static electric dipole moments of nondegenerate systems probe mass scales for physics beyond the Standard Model well those reached directly at high energy colliders. Discrimination between different models, however, requires complementary searches in atomic-molecular-and-optical, nuclear and particle physics. In this report, we discuss current status prospects near future a compelling suite such experiments, along with developments needed encompassing theoretical framework.
Particle physics today faces the challenge of explaining mystery dark matter, origin matter over anti-matter in Universe, neutrino masses, apparent fine-tuning electro-weak scale, and many other aspects fundamental physics. Perhaps most striking frontier to emerge search for answers involves new at mass scales comparable familiar below GeV-scale, or even radically below, down sub-eV scales, with very feeble interaction strength. New theoretical ideas address questions predict such feebly...
Axions and other very weakly interacting slim (with $m <$ 1 GeV) particles (WISPs) are a common feature of several extensions the Standard Model Particle Physics. The search WISPs was already recommended in last update European strategy on particle physics (ESPP). After that, case for has gained additional momentum. Indeed, may provide new paradigm to explain nature dark matter puzzling astrophysical observations. This document briefly summarizes current searches perspectives this research...
