Optimized lower bound on four-body hamiltonians (2006)
Benslama, A, Metatla, A, Bachkhaznadji, A, Zouzou, S R, Krikeb, A, Basdevant, J L, ...
Bourrely, C, Khuri, N N, Martin, A, Soffer, J, Wu Tai Tsun
For the energy of 14 TeV, to be reached at the Large Hadron Collider (LHC), we have had for some time accurate predictions for both the real and imaginary parts of the forward proton-proton elastic...
Bound states in two spatial dimensions in the non-central case (2003)
We derive a bound on the total number of negative energy bound states in a potential in two spatial dimensions by using an adaptation of the Schwinger method to derive the Birman-Schwinger bound in...
Yang-Mills theory for non-semisimple groups (2002)
For semisimple groups, possibly multiplied by U(1)'s, the number of Yang-Mills gauge fields is equal to the number of generators of the group. In this paper, it is shown that, for non-semisimple...
Neutrino masses from universal Fermion mixing (2002)
Gastmans, R, Osland, P, Wu Tai Tsun
If three right-handed neutrinos are added to the Standard Model, then, for the three known generations, there are six quarks and six leptons. It is then natural to assume that the symmetry...
Impact-Picture Phenomenology for $\pi^{\pm}p, K^{\pm}p$ and $pp, \bar{p} p$ (2002)
Bourrely, C, Soffer, J, Wu Tai Tsun
We present an extension to $\pi^{\pm} p$ and $K^{\pm} p$ elastic scattering at high energies of the impact-picture phenomenology we first proposed more than twenty years ago, for $p p$ and $\bar p p$...
Quantum memory: Write, read and reset (2002)
A model is presented for the quantum memory, the content of which is a pure quantum state. In this model, the fundamental operations of writing on, reading, and resetting the memory are performed...
Bound States in one and two Spatial Dimensions (2002)
Chadan, K, Khuri, N N, Martin, A, Wu Tai Tsun
In this paper we study the number of bound states for potentials in one and two spatial dimensions. We first show that in addition to the well-known fact that an arbitrarily weak attractive potential...
Theory and application of Fermi pseudo-potential in one dimension (2002)
The theory of interaction at one point is developed for the one-dimensional Schrodinger equation. In analog with the three-dimensional case, the resulting interaction is referred to as the Fermi...
Bound States in n Dimensions (Especially n = 1 and n = 2) (2001)
Khuri, N N, Martin, A, Wu Tai Tsun
We stress that in contradiction with what happens in space dimensions $n \geq 3$, there is no strict bound on the number of bound states with the same structure as the semi-classical estimate for...
Three-Neutrino MSW Effect and the LNW Mass Matrix (2001)
We review recent work on analytical solutions to the MSW equations for three neutrino flavours, for exponential and linear potentials. An application to a particular mass matrix is also discussed....
Impact-picture predictions for the $\gamma\gamma$ total cross section at LEP (2000)
Bourrely, C, Soffer, J, Wu Tai Tsun
We show that the rising total cross section $\sigma(\gamma\gamma \to hadrons)$ recently observed by the L3 and OPAL detectors at LEP is fully consistent with the impact-picture predictions. These...
Mikheyev-Smirnov-Wolfenstein Effect for Linear Electron Density (2000)
Lehmann, H, Osland, P, Wu Tai Tsun
When the electron density is a linear function of distance, it is known that the MSW equations for two neutrino species can be solved in terms of known functions. It is shown here that more...
Universal quark-lepton mixing and determination of neutrino masses (2000)
If three right-handed neutrinos are added to the Standard Model, then, for the three known generations, there are six quarks and six leptons. It is then natural to assume that the symmetry...
Solar Mikheyev-Smirnov-Wolfenstein Effect with Three Generations of Neutrinos (2000)
Under the assumption that the density variation of the electrons can beapproximated by an exponential function, the solar Mikheyev-Smirnov-Wolfensteineffect is treated for three generations of...
Collective effects from induced behaviour (1999)
We present a solvable model for describing quantitatively situations where the individual behaviour of agents in a group "percolates" to collective behaviour of the group as a whole as a result of...
On the Stability Domain of Systems of Three Arbitrary Charges (1998)
Krikeb, A, Martin, A, Richard, J M, Wu Tai Tsun
We present results on the stability of quantum systems consisting of a negative charge $-q_1$ with mass $m_{1}$ and two positive charges $q_2$ and $q_3$, with masses $m_{2}$ and $m_{3}$,...
Universality of low-energy scattering in (2+1) dimensions (1998)
Chadan, K, Khuri, N N, Martin, A, Wu Tai Tsun
We prove that, in (2+1) dimensions, the S-wave phase shift, $ \delta_0(k)$, k being the c.m. momentum, vanishes as either $\delta_0 \to {c\over \ln (k/m)} or \delta_0 \to O(k^2)$ as $k\to 0$. The...
Generalized gauge transformations: SU(2) Yang-Mills case (1995)
Gastmans, R, Newton, C, Wu Tai Tsun
We consider generalized gauge transformations for SU(2) Yang-Mills theory involving products of field operators at different space-time points. The infinitesimal gauge transformations are explicitly...
A new variant of symmetry breaking for quark mass matrices (1995)
Lehmann, H, Newton, C, Wu Tai Tsun
We propose a definite pattern for the breaking of a discrete flavor symmetry of the quark mass matrices which is caused by the masses of the first two generations of quarks. We discuss the...
Expanding protons seen by HERA (1994)
Bourrely, C, Soffer, J, Wu Tai Tsun
We show that the rising total photoproduction cross section recently observed at HERA is entirely consistant with the impact-picture in the theory of expanding protons which was proposed more than...
Masses of the Higgs boson and the top quark in the Standard Model from absence of divergences (1992)
