![]() In boson sampling and its variants ( 11, 12 ), nonclassical light is injected into a linear optical network, and the highly random, photon number and path-entangled output state is measured by single-photon detectors. We expect that the (invisibly decaying) muon-philic light (mX ≲ 2mμ) gauge boson can be probed down to gX ≲ 1.5 × 10−4(4.6 × 10−4, 2.3 × 10−4) for 50 (1, 10) ab−1 search. Boson sampling, proposed by Aaronson and Arkhipov ( 4 ), was the first feasible protocol for quantum computational advantage. The clean signal of muon-pair plus missing energy at Belle II can be a smoking gun for the new gauge boson. We show that the Belle II experiment has a robust chance to probe such a light boson in e+e− → μ+μ− + X channel and cover the most interesting parameter space explaining the discrepancy with the planned target luminosity, ∫dtL=50ab−1. ![]() ![]() We expect that the (invisibly decaying) muon-philic light (mX ≲ 2mμ) gauge boson can be probed down to gX ≲ 1.5 × 10−4(4.6 × 10−4, 2.3 × 10−4) for 50 (1, 10) ab−1 search.ĪB - Motivated by the long-lasting 3.5σ discrepancy in the anomalous magnetic moment of muon, we consider a new muon-specific force mediated by a light gauge boson, X, with mass mX < 2mμ and the coupling constant gX ∼ (10−4, 10−3). Players have to jump from platform to platform. The clean signal of muon-pair plus missing energy at Belle II can be a smoking gun for the new gauge boson. Thats pretty much what you get with Boson X, a slick, addictive arcade game thats been on rotation on my iPhone since it came out last year.

Use precise timing and fast reflexes to navigate a subatomic world where floors and ceilings don't exist. Build up speed inside a massive particle accelerator and generate high-energy collisions to discover strange new particles. ![]() We find that the most promising atomic systems where the X boson has an appreciable effect, distinguishable from a finite-nuclear-size effect, are muonic atoms of low and intermediate nuclear charge numbers.T1 - Search for muon-philic new light gauge boson at Belle II Quantum jump your way to critical velocity in Boson X: the rotational runner set in a particle collider. Use precise timing and fast reflexes to navigate a subatomic world where floors and ceilings don. High-precision atomic physics experiments aimed at observing the protophobic interaction need to separate the X boson effect from the nuclear-size effect, which is a problem because of the short range of the interaction (11.8 fm), which is commensurate with a “nuclear halo.” Here we analyze the X boson in terms of its consequences for both electronic atoms as well as muonic hydrogen and deuterium. Quantum jump from Planck to Planck as you hit critical velocity in Boson X, a new rotational runner from Mu & Heyo. This peak has been interpreted in terms of a protophobic interaction of fermions with a gauge boson ( X boson) of invariant mass ≈ 16.7 MeV which couples mainly to neutrons. Recently, a peak in the light fermion pair spectrum at invariant q 2 ≈ ( 16.7 MeV ) 2 has been observed in the bombardment of Li 7 by protons.
