We give the direction for use of a program which calculates the relativistic kinematics of a three body reaction with the target particle at rest in the laboratory frame. The program may also be used to study the decay of a particle into three bodies, the kinematics of a quasi two-body ...
2 Radiative three-body decays in QCD frameworks We review the kinematics of the radiative three-body decays in Sect. 2.1. We then work out the SM predictions using QCD factorization methods in Sect. 2.2, Low’s theorem in Sect. 2.3, and HHPT in Sect. 2.4. 2.1 Kinematics The general Lor...

The recent angular correlation measurement of the pair nucleons from the nonmesonic weak decay (NMWD) showed the dominant back‐to‐back (bb) kinematic events for both hypernucleiΛ5HeandΛ12C, which is the characteristic of the two‐body final state. However, it also revealed the significant...
Python-based simulation code for the three-body decay of a heavy neutral lepton (HNL). Includes tools for determining the lab-frame event kinematics of the final-state particles (assumed to be identical charged leptons that are produced along with a light neutrino). This assumes that the produc...
We develop a model for describing excited mesons decay into three mesons. The properties of the excited mesons can be extracted with this model. The model maintains the three-body unitarity that has been missed in previous data analyses based on the conventional isobar models. We study an import...
(2) Case II: Assuming that the distance between the two spectators in the initial state is normal but two Q quarks approach each other to form√a diquark during the decay pro- cess, then we set βQQ = 2βQQ¯ in the initial state and βQ Q = 2βQ Q¯ in the final state....

The molecular arrangement of 3 in the crystal was found to be a body-centered quasi-cubic structure (a ¼ bac), where each molecule of 3 in the unit cell center had eight nearest upside- down neighbors on the vertices of the unit cell, as shown in Fig. 4b and c. Interestingly, ...
The GH scalar can be produced in pairs through its QCD couplings to gluons, and may decay through higher-dimensional operators into a pair of heavy quarks. The signature is four b jets, forming two b¯b resonances of same mass [3, 4, 7–9]. Here we point out that an alternative ...
