We had previously obtained an integral equation for mesons in transverse lattice QCD, in the limit of large number of colours and strong transverse lattice gauge coupling [1]. This equation is a generalisation of the ’t Hooft equation [2], by inclusion of the spin degrees of freedom. We analyse this equation to extract spectral properties and light-front wavefunctions of mesons. We also extend ...

Previous measurements of the specific heat of helium-4 (4He) confined in all three spatial dimensions suggested a coupling between neighbor ing confinements through the tiny channels used to fill them [1]. Measurements of the superfluid fraction in the filling channels also suggested an enhancement attributed to their proximity to the larger regions of superfluid [1]. Recent measurements of con...

The smart antenna systems combine antenna arrays with digital signal processing (DSP) algorithms. In a smart antenna system a specialized signal processor computes the direction of arrival (DOA) of a user and also adds the strength of the signals from each antenna element together to form a beam towards the direction as computed by DOA. If additional users join in the system, the adaptive anten...

We show that manipulation and selection of optical patterns is possible by detuning the frequency of one of the two waves in counterpropagating photorefractive two-wave mixing with a feedback mirror. An analytical expression for the onset of modulational instability is derived for the general case of an arbitrary complex coupling constant, including a possible frequency shift of the generated s...

The advantages of using more than one renormalization group (RG) in problems with more than one important length scale are discussed. It is shown that: i) using different RG's can lead to complementary information, i.e. what is very difficult to calculate with an RG based on one flow parameter may be much more accesible using another; ii) using more than one RG requires less physical input in o...

A new world volume theory with a free scalar field was proposed for Multiple M2 branes recently. By giving the free scalar a large VEV, we can obtain a gauge theory of multiple D2 branes with a coupling constant proportional to the VEV. It is pointed out by Banerjee and Sen that we can get D2 branes by choosing a compactification in the θ direction, with radial position having the same value of...

The search for events containing isolated leptons (electrons or muons) and missing transverse momentum produced in ep collisions is performed individually and in a common phase space with the H1 and ZEUS detectors at HERA in the period 1994–2007. The presented H1+ZEUS data sample corresponds to an integrated luminosity of 0.97 fb, and comprises the complete high energy data from the HERA progra...

Evolution characteristics of a Kerr black hole (BH) are investigated by considering coexistence of disc accretion with the Blandford-Znajek process (the BZ process) and magnetic coupling of the BH with the surrounding disc (MC process). (i) The rate of extracting energy from the rotating BH in the BZ process and that in MC process are expressed by a unified formula, which is derived by using an...

We propose a microscopic theory of interaction of long wave molecular phonons with electrons in fullerides in the presence of disorder. Phonon relaxation rate and frequency renormalization are discussed. Finite electronic bandwidth reduces phonon relaxation rate at q = 0. Electron-phonon coupling constants with molecular modes in fullerides are estimated. The results are in good agreement with ...
