Besides the SM-like Higgs boson h, the Georgi–Machacek (GM) model predicts the existence of doubly-charged Higgs bosons H5±± in the 5-plet representation, which can be seen the typical particles in this model. We first used the latest Higgs boson diphoton signal strength data to find the allowed region at 2σ confidence level on the plane of the scalar mass values mH and the triple scalar coupling parameter ghHH, and then focus on the study of the triple Higgs production process e+e−→hH5++H5−− at the future International Linear collider (ILC). Our numerical results show that, the values of the production cross section are very sensitive to the triple Higgs coupling strength ghHH and can reach the level several fb in the reasonable parameter space. Considering the same-sign diboson decay H5±±→W±W±, the expected discovery reach at the future ILC experiments are also studied.

The singly charged and doubly charged Higgs bosons (H-+/- and H-+/-+/-) are the typical particles predicted in the Higgs Triplet Model (HTM) and the observation of these particles can be regarded as the direct evidence of the HTM. In this letter, we focus on the study of their associated production process: e(-)gamma -> nu eH+H--. The numerical results show that the production rates can reach the level of several fb. The characteristic signals and relevant SM backgrounds are also discussed in the case in which the vacuum expectation value of the triplet is around 1 GeV. As long as the singly and doubly charged Higgs bosons are not too heavy, their possible signals might be detected via this process in the future high-energy linear collider experiments.

The new scalars (H-+/-+/-, H-+/-+/- and H/A) are the typical particles predicted by the Higgs Triplet Model (HTM) and the observation of these particles can be regarded as the direct evidence of the HTM. In this letter, we study three pair production processes of these scalars, i.e., e(+)e(-) --> H++ H--, e(+)e(-) --> H+ H- and e(+)e(-) --> HA under the non-degenerate case. The characteristic signals and relevant SM backgrounds are also discussed both in the positive scenario (M-H/A > M-H +/- > M-H +/-+/-) and in the negative scenario (M-H/A < M-H +/- < M-H +/-+/-). Our numerical results show that the enhancement of the production rates due to the cascade decays is moderate in the positive scenario but significant in the negative one. Due to the relatively small SM backgrounds, their possible signals might be detected via these processes at future ILC experiments. Copyright (C) EPLA, 2015

The singly and doubly charged Higgs bosons (H ± and H ±± ) are the typical particles predicted in the Higgs Triplet Model and the observation of these particles can be regarded as the direct evidence of new physics. In this paper, we focus on the study of the singly and doubly charged Higgs bosons associated production process: e + e - → H + H -- W + . We present the production cross sections and the distributions of the transverse momenta and the rapidity distributions for outgoing particles. The numerical results show that the production rates can reach the level of several fb with reasonable parameter values. So, one can expect that enough signals could be produced in the future high-energy e + e - collider experiments. The relevant SM backgrounds are also discussed in the case that the vacuum expectation value of the triplet is around 1 GeV.

Besides the SM-like Higgs boson h, the Higgs triplet model (HTM) predicts the existence of charged and doubly charged Higgs bosons ( and ). In this letter, we focus on the study of the triple Higgs production in γγ collisions at the high-energy linear collider: and . We present the production cross-sections and the distributions of the various observables, i.e., the distributions of the energy and the transverse momenta of the SM-like Higgs boson and charged Higgs bosons. Our numerical results show that, with reasonable parameter values, the values of the cross-sections for two processes can reach the level of several tens of fb and hundreds of fb, respectively. Due to the small SM background, the possible signals of and might be detected via these processes in the future high-energy linear-collider experiments.

In this paper, we study the single neutral top-higgs (h t 0 ) production processes at the CERN Large Hadron Collider (LHC) and the International Linear Collider (ILC). At the LHC, the production rates of processes pp → Z(W)h t 0 are too small to detect h t 0 . However, with the reasonable parameter values, the cross sections can reach the level of 102 fb for qq → qqh t 0 process and 103 fb for top quark associated production process pp → th t 0 + X, respectively. At the ILC, we study the single top-higgs production processes e − γ → ν e W − h t 0 and γγ → W+W − h t 0 in e − γ and γγ collisions. It is found that the production cross sections can reach the level of a few fb with reasonable parameter values. Furthermore, such processes with the flavor-changing decay mode \(h_t^0 \to t\bar c\) might provide typical signatures to detected the top-higgs. Therefore, it is hopeful to find the signal of top-higgs at the LHC and ILC experiments via theses processes and test the TC2 model directly.

In the context of the topcolor-assisted technicolor (TC2) model, we study the productions of the charged top-pion associated with single top, charm or bottom quark in γp collision, which proceed via the subprocesses [Formula: see text], [Formula: see text] and [Formula: see text]. With the electron energy Ee = 50 GeV and photon energy Ep = 7 TeV , we find that the production rates can reach the level of several tens fb for [Formula: see text] production, and hundreds of fb for [Formula: see text] (or [Formula: see text]) productions. So one can expect that enough signals could be produced in the large part of the parameter space. Furthermore, these flavor-changing (FC) productions are extremely suppressed in the standard model (SM). With a large number of events and the clean background, the charged top-pion should be observable at the Large Hadron electron Collider (LHeC) based γp colliders. Thus, such charged top-pion production processes may offer a useful way to test the TC2 model.

Objective: To explore the effects of Folium Perillae injection on blood parameters after vascular bypass surgery in dogs.Method: Twenty hybridization dogs were randomly divided into high,middle,low dosage groups(1 434 mg/kg,478 mg/kg,159 mg/kg)and control.The common carotid artery was reconstructed with jugular vein from the same side by 45° bypass vascular surgery.Folium Perillae injection was intravenously administrated from brachiocephalic vein daily for 3 weeks.The blood parameters were detected at the 0,1,2,and 3 weeks after drug administration.Results: Compared with the control group,low,medium and high dosage of Folium Perillae injection could significantly decrease the whole blood viscosity and the whole blood reductive viscosity at low shear rate(10 s-1),erythrocyte aggregation index and erythrocyte electrophoresis index(P<0.05 or P<0.01).High dosage of Folium Perillae injection could significantly decrease the whole blood viscosity and the whole blood reductive viscosity at middle shear rate(60 s-1)(P<0.05),but low and middle dosage of Folium Perillae injection had no significant effects on the whole blood viscosity and the whole blood reductive viscosity at medium shear rate(60 s-1)(P>0.05).Low,middle and high dosage of Folium Perillae injection had no significant effects on hematocrit,plasma viscosity,erythrocyte rigidity index,the whole blood viscosity and the whole blood reductive viscosity at high shear rate(150 s-1).Conclusions: Folium Perillae injection could significantly improve the hemorrheological characteristics of dogs after vascular bypass surgery.

Vascular bypass grafting with autogenous vein is a frequent and important surgical procedure to cure vascular diseases and better promote blood supply in the clinical medicine. But the intimal hyperplasia(IH) has been one of the major cause of the graft late failure, especially for the middle and small artery. The pathology of IH is brief introduced. The Etiology of IH is discussed from the balance between proliferation and apoptosis, growth factor, hemodynamics and autologous vein itself. Prevention and cure of IH also are proposed.
