Particles and Nuclei International Conference 2017 (PANIC2017)

The next-generation B-factory experiment Belle II at the upgraded KEKB accelerator, SuperKEKB, will start physics data taking in 2018. It is an asymmetric e+e- collider that will operate with 40x the instantaneous luminosity of KEKB/Belle and aims to collect 50 times more data in total. Belle II offers the possibility to search for a large variety of dark sector particles in the GeV mass...

We report on the latest searches for low mass states predicted in several New Physics models performed with the data collected by the BaBar detector at the PEP-II e+e− collider. In particular, we search for single-photon events in a sample corresponding to 53 fb−1 of e+e− collision data. We look for events with a single high-energy photon and a large missing momentum and energy, consistent...

Many models beyond the Standard Model, motivated by the recent astrophysical anomalies, predict a new type of weak-interacting degrees of freedom. Typical models include the possibility of the low-mass dark gauge bosons of a few GeV and thus making them accessible at the BESIII experiment running at the tau-charm region. The BESIII has recently searched such dark bosons in several decay modes...

Understanding the properties of dark matter particle is a fundamental problem in particle physics and cosmology. The search of dark matter particle scattering off nuclei target using ultra-low background detector is one of the most promising technology to decipher the nature of dark matter. The XENON1T experiment, which is a dual phase detector with ~2.0 tons of xenon running at the Gran Sasso...

China Jinping underground laboratory (CJPL) is the deepest laboratory in the world and an ideal site for experiments on particle physics, astrophysics and other low background experiments. It is located in the Jinping Mountain near Xichang city, southwest China, with an overburden of about 2400m rock. The status of CJPL-I laboratory and progress of new CJPL-II project will be described. The...

The identification of dark matter is presently one of the greatest challenges in science, fundamental to our understanding of the Universe. Weakly Interacting Massive Particles (WIMPs) that arise naturally in several models of physics beyond the Standard Model are compelling candidates for dark matter. The Large Underground Xenon (LUX), operated at the Sanford Underground Research Facility...

Dark Matter elusiveness could be explained by speculating that it lives in a separate sector with respect to the Standard Model (SM) and that interacts with it only by means of messengers. The simplest model foresees just one messenger: a, possibly massive, vector boson given by a new U(1) symmetry. This mediator can faintly mix with the photon and, hence, interact with SM charged particles,...

Located at the INFN Laboratori Nazionali del Gran Sasso, Italy, DarkSide (DS) is a dark matter search project, which features a dual-phase liquid argon Time Projection Chamber as the WIMP detector, surrounded by an organic liquid-scintillator neutron veto and a water-Cherenkov muon veto. The current DS-50 has been running since 2013, initially with atmospheric Ar (AAr) and then, starting in...

The fixed points for the dynamical system in the phase space have been calculated with dark matter in the f(R) gravity models. The stability conditions of these fixed points are obtained in the ongoing accelerated phase of the universe, and the values Hubble parameter and Ricci scalar are obtained for various evolutionary stages of the universe. We present a range of some modifications of...

DarkSide-50 is a direct WIMP search underground experiment located at Gran Sasso, Italy. A detector with an active volume containing 50 kg of liquid argon, the DarkSide-50 Time Projector Chamber (TPC). The DarkSide-50 TPC is surrounded by a 30-ton boron-loaded liquid scintillator spherical neutron veto. This neutron veto is immersed in a 1,000 ton ultra-pure water, Cherenkov detector, acting...
