15. R value measurements at BESIII

Haiming HU (IHEP， CAS)

15/08/2022, 16:05

At BESIII, the $R$ value is measured with a total of 14 data points with the corresponding c.m. energy going from 2.2324 to $3.6710~\rm GeV$. The statistical uncertainty of the measured $R$ is less than 0.6%. Two different simulation models, the LUARLW and a new Hybrid generated, are used and give consistent detection efficiencies and initial-state-radiation corrections. An accuracy of better...

99. Current Status of Muon g-2 Experiment at Fermilab

The Fermilab Muon $g-2$ Experiment aims to make precise measurements of the anomalous magnetic moment ($a_{\mu}$) of the muon. The first measurement of the experiment is $3.3\sigma$ larger than the Standard Model (SM) prediction. The measurement is in good agreement with the previous result with improved precision. The uncertainty of the measurement is $0.46~ppm$ which gives the most precise...

55. Recent KLOE-2 results on entangled neutral kaons

Aleksander Gajos (J)

The entanglement of $K^0\bar{K^0}$ pairs produced in $\phi$-meson decays, in combination with the unique properties of the neutral kaon system – such as flavour oscillations, charge-parity (CP) and time-reversal (T ) violation – allows testing the basic principles of quantum mechanics and its fundamental discrete symmetries T , CP, CPT.

The KLOE and KLOE-2 experiments at the...

98. Effective field theories for doubly heavy hadronic molecules

Vadim Baru (Bochum University)

15/08/2022, 17:35

A short overview of the effective-field-theory approach for analysing the doubly heavy near-threshold states in the experimental line shapes is presented. Several applications to the LHCb pentaqurks, the bottomoniumlike states $Z_b(10610)$ and $Z_b(10650)$, and the $T_{cc}^+$ are discussed. The role of the one-pion exchange in the effective hadronic potential on the results is reviewed.
