New insight into prediction of phase behavior of natural gas hydrate by different cubic equations of state coupled with various mixing rules
Gas Hydrate, Cubic equation of state Mixing rule Thermodynamic modeling
2018/4/2
Progress in hydrate thermodynamic study necessitates robust and fast models to be incorporated in reservoir simulation softwares. However, numerous models presented in the literature makes selection o...
I review the present state of our knowledge about the masses and weak mixing elements of the u, d, s quarks. This is the written version of lectures given in the 1993 Theoretical Advanced Study Instit...
Two Comparative Case Studies of b-quark and c-quark Physics: • Particle-antiparticle Mixing • Radiative Weak Decays

We discuss prospects for detecting the two charm-related phenomena of $D^0$-${\bar D}^0$ mixing and weak radiative decays of $D$ mesons ({\it e.g.} $D\to K^* + \gamma$). A general update of particle-a...
We show that recent calculations of ΔI=3/2 effects in nonleptonic hyperon decay induced by md-mu≠0 are subject to significant model dependence. [S0556-2821(97)04819-4]

We determine the η-η′ mixing angle via a procedure relatively independent of theoretical assumptions by simultaneously fitting η,η′ reactions involving the anomaly η,η′→γγ, π+π-γ. We extract reasonabl...
Can nearby resonances enhance D-0-(D)over-bar(0) mixing?
Resonance mixing status the resonance parameters the resonance amplitude meson spectroscopy
2014/12/22
We study the contributions of resonances to mixing. Both and hybrid states are considered. Assuming reasonable values for the resonance parameters, we find relatively sizeable individual contributions...
Short-distance analysis of D-0-D-0 mixing
The standard model the quality of the neutral meson amplitude spiral
2014/12/20
We study the Standard Model short-distance prediction for the mass and lifetime differences between the two neutral D meson mass eigenstates. We find that, despite αs/4π suppression, next-to-leading o...
Quark and lepton masses and mixing in the landscape
Lepton yukawa coupling matrix element
2014/12/20
Even if quark and lepton masses are not uniquely predicted by the fundamental theory, as may be the case in the string theory landscape, nevertheless their pattern may reveal features of the underlyin...
We discuss Standard Model (SM) and New Physics (NP) descriptions of D0 mixing. The SM part of the discussion addresses both quark level and hadron level contributions. The NP part describes our recent...
New physics contributions to the lifetime difference in D-0-(D)over-bar(0) mixing
New physics model light quark mass
2014/12/20
We present the first general analysis of New Physics contributions to the D0-D̅ 0 lifetime difference (equivalently ΔΓD). We argue that New Physics (NP) contributions to |ΔC|=1 processes can domi...

We provide a comprehensive, up-to-date analysis of possible new physics contributions to the mass difference ΔMD in D0-D̅ 0 mixing. We consider the most general low-energy effective Hamiltonian a...
I begin by commenting on the most recent experimental compilation of D^0 mixing data, emphasizing the so-called 'strong phase' issue. This is followed by a review of the theory underlying charm mixing...

The physical model coupling fixed mixing the standard model the physical contribution
2014/12/19
We point out how, in certain models of new physics, the same combination of couplings occurs in the amplitudes for both D0-D̅ 0 mixing and the rare decays D0→ℓ+ℓ-. If the new physics ...

We present a theoretical analysis of the propagation of light pulses through a medium of four-level atoms, with two strong pump fields and a weak signal field in an N-scheme arrangement. We show that ...
It is argued that the experimentally observed quark decay of high generations to lower generations is due to the existence of a 5th force which explicitly violates the CP symmetry. The main supporting...
