Status and prospects of searches for neutrinoless double beta decay

The simultaneous beta decay of two neutrons in a nucleus without the emission of neutrinos (called neutrinoless double beta decay) is a lepton number violating process which is not allowed in the Standard Model of particle physics. More than a dozen experiments using different candidate isotopes and a variety of detection techniques are searching for this decay. Some (EXO-200, Kamland-Zen, GERDA) started to take data recently. EXO and Kamland-Zen have reported first limits of the half life $T_{1/2}^{0ν}$ for $^{136}$Xe. After a decade of little progress in this field, many new results will soo…

Status and Prospects of Discrete Symmetries Tests in Positronium Decays with the J-PET Detector

Positronium is a unique laboratory to study fundamental symmetries in the Standard Model, reflection in space ($\mathcal{P}$), reversal in time ($\mathcal{T}$), charge conjugation ($\mathcal{C}$) and their combinations. The experimental limits on the $\mathcal{C}$, $\mathcal{CP}$ and $\mathcal{CPT}$ symmetries violation in the decays of positronium are still several orders of magnitude higher than the expectations. The newly constructed Jagiellonian Positron Emission Tomograph (J-PET) was optimized for the registration of photons from the electron-positron annihilations. It enables tests of di…

Neutrinoless Double-Beta Decay: Status and Prospects

Neutrinoless double-beta decay is a forbidden, lepton-number-violating nuclear transition whose observation would have fundamental implications for neutrino physics, theories beyond the Standard Model and cosmology. In this review, we summarize the theoretical progress to understand this process, the expectations and implications under various particle physics models, as well as the nuclear physics challenges that affect the precise predictions of the decay half-life. We will also provide a synopsis of the current and future large-scale experiments that aim at discovering this process in physi…

Multi-hadron molecules: status and prospect

Starting from 2003, the discovery of a large amount of the so-called exotic hadronic states, i.e., the $XYZ$ states, the pentaquark states as well as the tetraquark states, have not only revived studies of hadron spectroscopy, but also hinted at the existence of new multi-hadron states made of hadrons other than nucleons and hyperons. We briefly comment on some of the latest studies on multi-hadron molecules in the light and heavy flavor sectors and highlight what should be done in the future.

The WITCH Experiment: towards weak interactions studies. Status and prospects

WITCH实验的主要目标是测试β衰变中标量或张量类型相互作用的可能混合物的标准模型。这一信息将从反冲能谱的形状中推断出来。实验装置已经完成，正在ISOLDE（欧洲核子研究中心）进行密集调试。它结合了一个潘宁阱来存储离子和一个延迟谱仪来探测反冲离子的能量。简要概述了WITCH设置和迄今为止执行的调试测试结果。最后，展望物理程序进行了审查。

The N* Program at Jefferson Lab - Status and Prospects

本文讨论了非奇异重子共振区中介子的电生和光生的最新结果。从基态核子到Delta（1232）的四极跃迁的结果表明了π云对解释观察到的四极跃迁多极的重要贡献。目前正在利用非极化截面测量和束自旋不对称性研究单π介子生产中的“罗珀”共振的激发。关于S_{11}（1535）跃迁形状因子的新结果现在给出了在大的Q2范围内一致的图像。电生成p π ^+ π ^-的第一个结果显示了侵入共振结构。这在使用已知共振特性的等压线模型拟合中难以解释，并且可能暗示“缺失”共振的激发。对K^+ λ共振的研究也揭示了类似共振的行为。我简要地解决了一个新的途径N* 物理使用独家深虚拟康普顿散射，最近首次在JLAB和DESY测量。
