Abstract We propose a new dihedral angle observable for measuring the CP property of interaction between top quark and Higgs boson in production at 14 TeV Large Hadron Collider (LHC). consider two decay modes boson, $H\to b\bar{b}$?> \gamma\gamma$?> , demonstrate that distribution is able to distinguish CP-even CP-odd hypothesis 95% confidence level, with an integrated lum...

We reported a 71 years old woman, with history of rest and postural tremor, bradykinesia and memory problems. In her dynamic MRI, a contrastenhanced tumor in the cerebellopontine (CP) angle was found which was compatible with a meningioma. 99mTc-TRODAT SPECT showed decreased activity in the left putamen, indicating idiopathic Parkinson disease. There was also a focus of increased activity on th...

With the discovery of CP violation in the decays of neutral B mesons 1 and the precise measurement 2 of the angle β of the Cabibbo-Kobayashi-Maskawa (CKM) Unitarity Triangle 3, the experimental focus at the B factories has shifted towards over-constraining the unitarity triangle through precise measurements of |Vub| and the angles α and γ, and towards measurements of CP asymmetry in the charmle...

Assuming that the axion mechanism of solving the strong CP problem does not exist and the vanishing of θ at tree level is achieved by some model–building means, we study the naturalness of having large CP–violating sources in the leptonic sector. We consider the radiative mechanisms which transfer a possibly large CP-violating phase in the leptonic sector to the θ parameter. It is found that la...

In the case of large 1-3 mixing angle as sin 2θ13 ≥ 0.03, we investigate the possibility for measuring the leptonic CP phase by using only νμ → νμ oscillations independently of νμ → νe oscillations. As the result, we find that the CP phase can be measured best around the energy E = 0.43GeV and the baseline length L = 5000km without strongly depending on the uncertainties of other parameters. In...

Mixed tumors composed of schwannoma and meningiomas are extremely rare and are usually associated with neurofibromatosis-2 (NF-2). So far, all the cases reported have involved the cerebello-pontine angle. Only two cases did not have a clear association with NF-2. We report a mixed tumor comprising of meningioma admixed with schwannoma in a 33-year-old male with bilateral trigeminal nerve schwan...

Vestibular Shwannomas are responsible for 80-90% of the cerebelar-pontine angle tumors and their incidence is of 0.8 to 20.5% of all tumors. Unilateral and progressive hearing loss is the most frequent and premature symptom, and tinnitus is the second most common complaint. Only 5% of the patients have normal audiograms. In this case the patient complained of ipsilateral facial numbness and wea...

Cranial computed tomography (CT) scans of 1,600 head trauma patients, 67 of which demonstrated evidence of brainstem injury, were reviewed. CT diagnosis of brainstem injury was based on direct and indirect evidence. Direct signs, which include focal hemorrhage, significant intraparenchymal contrast enhancement, hemorrhagic contusion, and edema of the brainstem, appear as areas of high density, ...

BACKGROUND AND PURPOSE Although the 12-minute 3D fast asymmetric spin-echo (FASE) protocol for imaging the inner ear has been satisfactory, reducing imaging time to minimize patient discomfort and maximize system throughput is desirable. We therefore evaluated the performance of a zero-fill interpolated (ZIP) fast recovery 3D FASE sequence in screening for cerebellopontine (CP) angle lesions in...
