Three-body resonances in the φ 4 theory
Journal of High Energy Physics, 2023 We study the properties of three-body resonances using a lattice complex scalar φ 4 theory with two scalars, with parameters chosen such that one heavy particle can decay into three light ones.

The isospin-3 three-particle K-matrix at NLO in ChPT
Journal of High Energy Physics, 2023 The three-particle K-matrix, K df , 3 $$ {\mathcal{K}}_{\textrm{df},3} $$ , is a scheme-dependent quantity that parametrizes short-range three-particle interactions in the relativistic-field-theory three-particle finite-volume formalism. In this work, we

The PANDA Experiment at FAIR - Subatomic Physics with Antiprotons
, 2016 The non-perturbative nature of the strong interaction leads to spectacular phenomena, such as the formation of hadronic matter, color confinement, and the generation of the mass of visible matter.

Opportunities, Challenges, and Fantasies in Lattice QCD [PDF]
, 2002 Some important problems in quantitative QCD will certainly yield to hard work and adequate investment of resources, others appear difficult but may be accessible, and still others will require essentially new ideas.

Quarkonium and Charm Hadrons : New Results on Spectroscopy in BaBar [PDF]
, 2006 We report on recent results in spectroscopy from BaBar. This includes the discovery of a new $\Lambda_c$ baryon, detailed studies of the $D^*_{sJ}(2317)^+$, $D_{sJ}(2460)^+$, X(3872) and Y(4260) particles and the first measurement of hadronic non-$B\bar ...

Free Muons and Muonium - Some Achievements and Possibilities in Low Energy Muon Physics
, 2002 Some recent precision experiments in low energy muon physics are discussed. Spectroscopy on the muonium atom, the bound state of a positve muon and an electron, has provided precise tests of standard theory and yielded most precise values of important ...

Finding interaction mechanism between exotic molecule and conventional hadron
Physics Letters BAn intriguing and important question arises: how do hadronic molecules interact with conventional hadrons? In this work, we propose a novel mechanism to address this issue, focusing on the interactions between hidden-charm molecular pentaquarks (Pc) and ...

Studies of Parity Violation in Atoms
Annalen der Physik, Volume 537, Issue 2, February 2025.This article provides an overview of atomic parity violation (APV), emphasizing its role in testing the Standard Model and probing new physics. The review discusses manifestations of APV, including nuclear‐spin‐independent and dependent effects, and explores isotopic comparison as a method for precision measurements.
