12. Charmed mesons production asymmetries with early Run 3 data from LHCb

Paula Herrero Gascón (Heidelberg University)

The dataset collected by the LHCb collaboration during Run 1 and Run 2 has played a major role in the progress of charm physics. For Run 3 of the LHC, the LHCb detector was upgraded to operate at higher instantaneous luminosities. This talk presents the first results obtained with early Run 3 data, measuring the production asymmetries of $D^0$, $D^+$, and $D_s^+$ charm and anticharm mesons in...

2. Hadronic charm decays and CP violation

Fu-Sheng Yu (Lanzhou University)

I will talk about the general aspect of charm CPV and then focus on the recent progresses on CPV of charmed baryons.

3. Hadronic decays of charmed mesons and CP violation

Hai-Yang Cheng (Academia Sinica)

In this talk I'll give an overview of the two-body decays of charmed mesons
and their CP violation. Recent developments in $D\to VP$ and $VV$ decays
are discussed. Attention is paid to the enigmas occurred in recent measurements
of $D\to VV$. The long-distance penguin, which is the key ingredient responsible for direct CP violation in $D\to PP$ and $VP$, is emphasized and elaborated on.

7. Progress of the Super Tau Charm Facility in China

Cong Geng (Sun Yat-sen University)

The Super Tau Charm Facility (STCF), a planned symmetric electron-positron collider in China, aims to facilitate $e^+e^−$ collisions across a center-of-mass energy range of 2 to 7 GeV, targeting a peak luminosity of $0.5×10^{35}\mathrm{cm}^{−2}\mathrm{s}^{−1}$. With an anticipated annual integrated luminosity exceeding $1~ab^{−1}$, the STCF is poised to generate vast datasets. These will...

9. Rare and radiative decays of charm with Belle and Belle II

Dr Seema Bahinipati (IIT Bhubaneswar)

With high statistics data samples collected in a relatively clean
environment in e+e- collisions, a strong program in searches for rare
processes is enabled at the Belle and Belle II experiments. The
excellent detector performance allows for precision measurements to push
the boundaries of exploration for hints of physics beyond the Standard
Model through studies of rare and suppressed...

4. Testing the light scalar meson as a non-$q\bar q$ state in semileptonic $D$ decays

Yu-Kuo Hsiao (Shanxi Normal University)

While the light scalar mesons ($S_0$) are considered to be either ordinary $q\bar q$ or exotic tetraquark states, we investigate the semileptonic decays $D\to S_0 e^+\nu_e$, by taking into account the resonant effects of $S_0\to M_1 M_2$, where $S_0=a_0(980)$, $f_0(980)$, and $f_0(500)/\sigma_0$, and $M_{1(2)}$ represents a pseudoscalar meson. The $D\to S_0$ form factors in the different quark...

10. The LHCb upgrade II

Emanuele Santovetti (University of Rome "Tor Vergata" and INFN)

The Upgrade II of the LHCb experiment is proposed for the long shutdown 4 of the LHC. The upgraded detector will operate at a maximum luminosity of 1.5×1034 cm-2 s-1, with the aim of reaching a total integrated luminosity of ∼300 fb-1 over the lifetime of the HL-LHC. The collected data will probe a wide range of physics observables with unprecedented accuracy, with unique sensitivities for the...

1. The Role of Nonperturbative Dynamics in 𝐷𝐷̄ Mixing

Prof. Blazenka Melic (Rudjer Boskovic Institute Zagreb)

We will address the role of nonperturbative QCD in D-Dbar mixing.
