Many theoretical models of the most profound unexplained phenomena in the universe predict modifications to the inverse square law of gravity at sub-millimeter length scales, yet this law has not been tested below 50 microns and there could be forces of nature millions of times stronger than gravity acting at this range. Following a general introduction, I describe a series of experiments...

We report on new experimental constraints on gravity-like fifth forces by measuring the angular distribution of cold neutrons scattering off atomic xenon gas. The results improve previous upper limits on Yukawa-type parametrization space in the 4 to 0.04 nm range by a factor of up to 10, which was published in PRL 114, 161101 (2015). In this presentation, we also discuss about our new plans of...

The accelerating expansion of the universe has been recently discovered and confirmed. It is one of the most puzzling observation of modern cosmology: 70% of the energy budget of the Universe today has to be attributed to a completely unknown type of Dark Energy. One theoretical route to address this problem is to assume the existence of a cosmological scalar field, the quintessence, with...

A measurement of the ground-state hyperfine structure (GS-HFS) of antihydrogen can become one of the most sensitive tests of CPT symmetry on an absolute scale due to the fact that it is a small quantity on the energy scale and can be measured to very high precision. For this reason the ASACUSA collaboration at the Antiproton Decelerator of CERN has chosen to perform a measurement of GS-HFS...

On September 14 2015 the two LIGO detectors registered at almost the same time an event consistent with gravitational wave emission by the merger of two black holes. The reconstructed waveform of the signal shows that the system was located at a distance of approximately 400 Mpc, with constituent masses of 36 and 29 M_sun. The final object is consistent with a mass of 62 M_sun and then...

The neutrino anomalies generally refer to the hints from appearance and disappearance experiments for eV-scale neutrinos. In the 1990s, the LSND experiment reported a neutrino appearance oscillation signal that, when viewed together with the solar and atmospheric neutrino oscillation experiments, is in conflict with the Standard Model expectation of three neutrino flavors. The follow-on...

Despite a long history the sterile neutrino issue is still currently a very open issue.

Past reactor and source experiments have observed deficits of neutrinos, with respect to the expected rates, that could be explained by the existence of a sterile neutrino at the 1 eV mass scale.

The two sources of parity nonconservation (PNC) in atomic systems are the neutral current weak (NCW) interactions due to the exchange of the Z boson between the nucleus and the electrons and the nuclear anapole moment. The NCW interactions can give rise to nuclear spin independent (NSI) as well as nuclear spin dependent (NSD) PNC, while the interaction of the nuclear anapole moment with the...

Many systems are used to search for a non-zero electric dipole moment such as atoms, molecules or neutron. The existence of static T-odd and P-odd moments of a nucleus can arise from T and P violating nucleon-nucleon interactions. Measuring the EDM of an atom, the sensitivity on those interactions depends on the nuclear structure. In particular pear-shaped nuclei are predicted to be good candidates.

Permanent electric dipole moments (EDMs) of elementary particles are good candidates to search for the combined charge conjugation and parity symmetry (CP) violation. At the Cyclotron and Radioisotope Center at Tohoku University, an experiment to search for the EDM of the electron using francium (Fr) atoms is promoted. The progress and the present status of the facility will be presented.

Due to their outstanding property to be storable and hence observable for long periods of time (several hundreds of seconds) in suitable material or magnetic traps, ultra-cold neutrons (UCN) with energies around 100 neV are an unique tool to study fundamental properties of the free neutron, like its beta-decay lifetime, its electric dipole moment and its wave properties.

Why is there so much matter and so little anti-matter observed in our Universe? One necessary condition to create a matter/antimatter asymmetric universe from symmetric starting conditions is a sufficient strong source of charge/parity violation (CPV) in the fundamental physics describing the early universe.

The K+->pi+nunu decay is one of the theoretically cleanest meson decay where to look for indirect effects of new physics complementary to LHC searches. The new experimental setup used by the NA62 experiment at CERN SPS since 2014 is designed to measure the branching ratio of this decay with 10% precision. NA62 took data with the new setup in 2014, 2015 and 2016. The quality of data acquired in...

One of general feature of Grand Unified Theories (GUTs) is their prediction of the instability of nucleons by baryon number violating decays. Therefore, nucleon decay search is one of keys to open new door beyond the Standard Model.The Super-Kamiokande detector is the best detector to search for nucleon decays. In this talk, I'll report the latest results from Super-Kamiokande.

Muonium is a hydrogen-like atom consisting of a positive muon and an electron. Precision spectroscopy of its ground state hyperfine splitting (HFS) is the most rigorous test of bound-state QED and the most precise determination of the muon mass. At J-PARC, MuSEUM collaboration intends to improve the precision of muonium HFS by one order of magnitude relatively to the most recent experiment. In...

A precise understanding of the beta spectrum shape proves an indispensable tool in the pursuit of Beyond Standard Model (BSM) physics. It opens up possibilities for scalar and tensor current searches and allows a study of nuclear structure dependent effects through the weak magnetism interaction [N. Severijns et al. Rev. Mod. Phys. 78, 991-1040 (2006)]. The latter is a contamination of the...

Very precise measurements in nuclei can offer demanding tests of the Standard Model. In particular, superallowed nuclear beta-decay between 0+ analogue states is a sensitive probe of the vector part of the weak interaction, with the established strength – or F t value – of each such transition being a direct measure of the vector coupling constant, GV. Each transition’s F t value depends on...

Replacing the classical groups in the Standard Model (SM) by their quantum group counterparts is motivated from the consideration of both Lie and Hopf type (quantisation) deformations. A quantisation deformation deforms the universal enveloping algebra of a Lie algebra into a quantum group.
