The discovery of a new boson with a mass of approximately 125GeV in 2012 at the Large Hadron Collider1–3 has heralded a new era in understanding the nature of electroweak symmetry breaking and possibly completing the standard model of particle physics4–9. Since the first observation in decays to γγ, WW and ZZ boson pairs, an extensive set of measurements of the mass10,11 and couplings to W and ...
It is shown that field-theory based single boson exchange potentials cannot be identified to those of the Yukawa or Coulomb type that are currently inserted in the Schrödinger equation. The potential which is obtained rather corresponds to this current single boson exchange potential corrected for the probability that the system under consideration is in a two-body component, therefore missing ...
We discuss the strength of the trilinear Higgs boson coupling in technicolor (or composite) models in a model independent way. The coupling is determined as a function of a very general ansatz for the technicolor self-energy, and turns out to be equal or smaller than the one of the standard model Higgs boson depending on the dynamics of the theory. With this trilinear coupling we estimate the c...
The possibility of detecting a Higgs boson through several production and decay channels is instrumental to the measurement of its couplings. In this paper we study the pp → tt̄H, H → τ+τ− channel at the LHC, for the case of a scalar Higgs boson, and use the obtained results to improve on existing strategies toward a model independent determination of the Higgs boson couplings. The case of a sca...
Background:
 To study the nuclear structure, a novel model known as interacting boson model-one (IBM-1) is utilized. It hypothesized that low-lying collective quadrupole states can be produced of an N-boson system capable occupying two levels, other with angular momentum J = 0 and one 2.
 Materials Methods:
 We investigated structure Molybdenum in theoretical context. utilized In...
