We study the production and decay of the neutral top-pion π0 t predicted by topcolor-assisted technicolor(TC2) theory. Our results show that, except the dominant decay modes bb̄, t̄c and gg, the π0 t can also decay into γγ and Zγ modes. It can be significantly produced at high energy e+e− collider(LC) experiments via the processes e+e− → π0 t γ and e+e− → Zπ0 t . We further calculate the producti...

During embryogenesis, the activated Torso receptor tyrosine kinase (TOR RTK) pathway activates tailless (tll) expression by a relief-of-repression mechanism. Various lines of evidence have suggested that multiple factors are required for this repression. We show that Tramtrack69 (TTK69) binds to two sites within tll cis-regulatory DNA, TC2 and TC5, and that TTK69 is phosphorylated by mitogen ac...

Five phase transitions of [Cd(DMSO)6](ClO4)2 have been detected by differential scanning calorimetry, namely the three reversible transitions: stable KIa ↔ stable KIb at TC4 = 242 K, due to a change of the crystal structure, metastable KII ↔ metastable KIII at TC3 = 318 K, and metastable KII ↔ overcooled K0 at TC2 = 347 K, one irreversible transition: KIa → K0 at TC1 = 376 K, and melting at Tt ...

In the framework of top-color assisted technicolor(TC2) theory, we study the four decay processes of charged top-pion, i.e., Π+t → tb, Π+t → cb, Π+t → Wγ, Π+t → WZ, the decay branching ratio of these modes are calculated. The results show that the main decay channels of charged top-pion are the tree level modes: Π+t → tb̄ and Π+t → cb̄. Light Π+t is easier to be detected than heavy one at future ...

The coupling of phonons with collective modes and single-particle gap excitations associated with one (1d) and two-directional (2d) electronically-driven charge-density wave (CDW) ordering in metallic RTe3 is investigated as a function of rare-earth ion chemical pressure (R=Tb, Dy, Ho) using femtosecond pump-probe spectroscopy. From the T -dependence of the CDW gap ∆CDW and the amplitude mode (...

Five solid phases of [Co(DMSO)6](BF4)2 have been detected by differential scanning calorimetry (DSC). Phase transitions were detected between the following solid phases: stable KIb ↔ stable KIa at T C4 = (328± 2) K, metastable KIII ↔ undercooled phase K0 at TC3 = (383± 4) K, metastable KII ↔ undercooled K0 at TC2 = (399± 2) K and stable KIa ↔ stable K0 at TC1 = (404± 1) K. The title compound me...
