Special Transitions

Cold molecular ions prepared by sympathetic cooling with laser-cooled atomic ions in an ion trap represent attractive systems for new spectroscopic experiments. The long trapping times (up to hours) and state lifetimes (up to minutes) [1,2] in an almost perturbation-free environment enable the long interaction times required for the study of “forbidden” spectroscopic transitions which have not...

Antihydrogen

Extra fundamental short-range interactions mediated by new bosons are predicted in many extentions of the Standard Model of particle physics. They are also predicted in theories with large extra spatial dimentions and theories involving the light dark matter hypothesis.

To search for such interactions at different charateristic distances, the experimentalists use many methods including...

We describe recent developments in tests of quantum-electrodynamics (QED),
the theory of the interactions of matter with electro-magnetic fields and forces. The tests focus on consistency in the determination of parameters or constants within QED obtained via multiple independent means and, in particular, by comparisons of precision measurements with, equivalently accurate, theoretical...

Single particles in traps allow for clean investigations of basic interactions and also for the determination of fundamental constants. This has been demonstrated by investigations of Quantum Electrodynamics (QED) with respect to the g-factor of the free electron [1] and of hydrogen-like or lithium-like ions [2 - 4], which form the most precise determinations of the fine-structure constant and...

33. The relativistic and radiative corrections to polarizability of hydrogen-like atoms

Dr Wanping Zhou (School of Physics and Technology, Wuhan University, china)

poster contribution

Poster Session, Monday

The polarizability in atomic physics is important to determining the frequency standard [1], magic wavelengths and the tune-out wavelengths [2,3] of the atom in the optical lattice clock. It is also used to calculating the long-range interactions between atoms [4], in the cold atom research. However the higher order corrections are still researched inadequately [1,5].

Poster Session, Monday

We consider bound states between an atomic nucleus and a muon,
so called muonic atoms. Especially for high charge numbers, the sur-
rounding atomic electrons do not influence the muon and the system
is essentially hydrogenlike. Just as in normal atoms, there is fine and
hyperfine splitting, but the significance of the various contributions
differs dramatically. In particular, nuclear...

We present a new method of spectroscopy, utilizing a drift effect to disperse
charged particles in a uniformly curved magnetic field. The curved field results
in a drift of the charged particles perpendicular to the radius of the curvature
and to the magnetic field, which is proportional to the particle’s momentum.
A spatial-resolving detector will determine the momentum spectra.

Laser spectroscopy of atomic hydrogen is a source of valuable data for a least-square adjustment of fundamental constants and precise tests of QED.

In diatomic systems, the rich and varied spectra and nearly degenerate energy levels provide huge enhancements for tiny physical effects, making it possible to look for new physics beyond the Standard Model in a single experiment. Nuclear-spin dependent parity-violating interactions and nuclear-anapole-moment effects in diatomic molecules in particular provide precise test of the electroweak...

The 1S-2S two-photon transition frequency in hydrogen can be measured most accurately compared to other transitions in hydrogen due to its narrow natural linewidth, and serves as a corner stone for fundamental constants.

Positronium & Muonium

Positronium is an excellent system to test bound state QED theory to very high precision, since it is almost exlusively governed by the electromagnetic force and does not exhibit the finite size effects which plague measurements of protonic atoms.

Casimir & Cosmology

We study, using the formalism proposed by Dalibard, Dupont-Roc, and Cohen-Tannoudji, the resonance interatomic energy (RIE) of two identical two-level static atoms in a symmetric/antisymmetric entangled state, which are coupled to massless scalar fields, in a number of different spacetimes. We first show that the presence of a boundary in a flat Minkowski spacetime can dramatically modify the...

This is a Precision measurement plays an important role in unveiling new physics by probing beyond the known boundaries of knowledge. In a similar footing, it has a wide range of application in trade and commerce. From fundamental physics viewpoint, the Standard Model (SM) of particle physics though considered to be the most celebrated model in physics is known to have shortcomings as is...

The accuracy of the molecular spectroscopy on weak transitions (too weak to saturate) in molecules which cannot be cooled and trapped, is presently limited to the sub-megahertz level, without clear perspectives for further substantial improvements. We demonstrate a new method with the potential to achieve kilohertz-level accuracy. We bring the Doppler-regime measurements into the high-pressure...

The dissociation energy (D$_0$) of H$_2$ is a benchmark value in quantum chemistry, with recent QED calculations now approaching accuracies achievable in simple atoms. Precise measurement of the GK-X molecular transition, in combination with other precision measurements, provides a determination of D$_0$. The GK-X transition is excited through Doppler-free two-photon spectroscopy using 179-nm...

The BESIII experiment at BEPCII accumulated the world's largest $e^+e^-$ collision samples at 3.773 and 4.178 GeV. We have studied the purely leptonic decays $D^+_{(s) }\to l^+v$, and the semi-leptonic decays of $D^0\to K(\pi)^-e^+v_e$, $K(\pi)^-\mu^+v_\mu$, $D^+\to\bar K^0(\pi^0)e^+v_e$, $\bar K^0(\pi^0)\mu^+v_\mu$ and $D_s^+\to K^{(*)0}e^+v_e$. We will report the improved measurements of the...

After a short review of the overall physics program of BESIII and the key features of the BEPCII collider and BESIII detector, I will present some of the recent highlights of the charmonium(-like) spectroscopy program of BESIII. The results include measurements of radiative and hadronic decays of several charmonium(-like) states below and above the open-charm production threshold. The ultimate...

The construction of the low-energy $e^+e^-$ collider ($\mu\mu$tron)
operating near the muon-pair production threshold begins in 2018 at
BINP (Novosibirsk). The collider parameters and configuration
(a luminosity of $8\times 10^{31}$ cm$^{-2}$c$^{-1}$), an center-of-mass
energy spread of 400 keV, and beams collision with a large crossing angle)
allow to perform experiments on study of dimuonium...

Spherical neutral detector (SND) is an experiment for $e^{+}e^{-}$ annihilation study at moderate energies 0.2-2 GeV. The light quark anti-quark bound states are main subject of study at these energies. The quark anti-quark states express themselves as resonances in the e+e- ->hadronic cross sections. The hadronic cross sections could be recalculated to hadronic vacuum polarization (HVP). The...
