5. Fundamental oscillation modes of self-interacting bosonic dark stars

陳 樫旭 (淡江大學)

29/06/2019, 11:00

We perform a detailed analysis of the fundamental f-mode frequencies and damping times of nonrotating stellar-mass boson stars in general relativity by solving the nonradial perturbation equations. Two parameters which govern the microscopic properties of the bosonic condensates, namely the self-coupling strength and the mass of the scalar particle, are explored. These two quantities...

8. The Quest for Neutrino Mass Ordering

王 为 (中山大学)

29/06/2019, 12:50

Neutrino mass is currently the only sign of new physics beyond the Standard Model (SM) of particle physics. Unfortunately, due to the challenges in measuring the three absolute neutrino masses, we currently only know the two mass-squared differences manifested in neutrino oscillation data. The mass ordering is very likely to be the first experimental handle we could have on physics related to...

20. Extension of scalar-tensor theories and spatially covariant gravity

高 显 (中山大学)

30/06/2019, 12:50

In order to explain the accelerated expansion of our universe in its early stage and today, the most popular approach is to introduce a scalar field to drive the inflation or to act as dark energy. This is the so-called scalar-tensor theory of gravity. In this talk, we first review the development of the scalar-tensor theories with higher derivatives in the recent years. Then we introduce the...

27. Direct CP violation in charmed meson decays

鄭 海揚 (中央研究院物理研究所)

01/07/2019, 10:30

In 2012 Cheng-Wei Chiang and I have studied direct CP violation in singly Cabibbo-suppressed D decays within the topological diagram approach. We concluded that the direct CP asymmetry difference \Delta A_{CP} between D0 -> K+ K- and D0 -> pi+ pi- is about (-0.139+/- 0.004)\% and (-0.151+/-0.004)\% for the two solutions of W-exchange amplitudes, respectively. The first observation of CP...

28. The QCD trace anomaly in the hadron

杨 一玻 (中科院理论物理所)

01/07/2019, 11:00

The QCD trace anomaly is the basic anomaly to make the massless hadron in the chiral limit to be massive. Its contribution to the hadron is predicted by the sum rule, while the direct calculation or experimental determination is absent util recently. I will show the theoretical progress and discuss the possible experimental opportunities.

29. Interactions between two heavy mesons within chiral perturbation theory

刘 占伟 (兰州大学)

01/07/2019, 11:30

We have studied the interactions between two heavy mesons [D^()-D^() or B^()-B^()] within heavy meson chiral effective field theory. The effective potentials are calculated with Weinberg's scheme up to one-loop level. At the leading order, four body contact interactions and one pion exchange contributions are considered. In addition to two pion exchange diagrams, we include the one-loop...

30. Threshold resummation at subleading power

王 健 (山东大学)

01/07/2019, 12:20

We derive a threshold resummation formula at next-to-leading power employing the soft-collinear effective theory. The anomalous dimensions of subleading-power soft functions are calculated directly. As a result, we resum the leading logarithms near the kinematic threshold. Expansion of the resummed result leads to the leading logarithms at fixed orders, providing new results at the five-loop...

31. A study of the pentaquark states

肖 楮文 (Central South Univesity)

01/07/2019, 12:50

The LHCb collaboration has reported recently three pentaquark states found in the J/ψN mass distribution. Based on the constraints of the heavy quark spin symmetry combined with the local hidden gauge symmetry, we investigate the D(∗)Σ(∗) interactions, together with J/ψN and other coupled channels, using a coupled channel approach. From the poles found in the second Riemann sheets, we...
