Quantum Physics is the branch of physics that studies the behavior of matter and energy at the smallest scales, typically at the level of atoms and subatomic particles. It encompasses principles such as wave-particle duality, quantization, and the uncertainty principle, fundamentally challenging classical physics concepts.

We study the implications of minimal flavor violating low energy supersymmetry scenarios for the search of new physics in the B and Higgs sectors at the Tevatron collider and the LHC. We show that the already stringent Tevatron bound on... more
The conventional method using "Low Energy Theorems" derived by Chanowitz et al. [3] does not seem to lead to explicit unitarity limit in the scattering processes of longitudinally polarized gauge bosons for the high energy case in the... more
DJP continues to optimize the collection of tax returns by facilitating a technology-based tax service system, one of which is e-filing that has been running since 2016. However, e-filing turned out to have less influence on the delivery... more
In the nowadays Science of Classic Physics, Einstein's Relativity theories are the leading acceptable theories of the Classic Physics. However, the nowadays Science of Physics still embeds unresolved Paradoxes, incompatibilities between... more
We consider the processes e + e -→ ℓ + ℓ ′-ν ν′ , including all the possible charged lepton combinations, with regard to measuring parameters characterizing the W boson. These reactions all proceed via virtual W pair production as well as... more
We consider the possibility that physics beyond the standard model contributes to the decays B → V 1 V 2 , where V 1 and V 2 are vector mesons. We show that a time-dependent angular analysis of B → V 1 V 2 decays provides many tests for... more
Recently, it was argued that new-physics (NP) effects in B decays can be approximately parametrized in terms of a few quantities. As a result, CP violation in the B system allows one not only to detect the presence of new physics (NP),... more
We study the decays of heavy chiral (t ′ , b ′ ) quarks in a four-generation extension of the Standard Model. If the difference between the t ′ and b ′ masses is smaller than the W ± mass, as favored by precision electroweak measurements,... more
We present a new and sensitive method to observe direct CP violation in D mesons using Bose symmetry and Dalitz plot. We apply the method to processes such as B → D 0 D 0 P , where P is either a K or a π. By choosing to reconstruct D... more
We present a technique to determine the CP violating phases, as well as, the lifetime differences of the mass eigenstates for both B d and B s , by considering correlated B B pairs produced at the Υ resonances. We do not require a... more
It is well known that one can use B → ππ decays to probe the CP-violating phase α. In this paper we show that these same decays can be used to search for new physics. This is done by comparing two weak phases which are equal in the... more
The short-distance Hamiltonian describing b → s(d)e -e + in the standard model is used to obtain the decay spectrum of B → K -π + e -e + and B → π -π + e -e + , assuming the Kπ and ππ systems to be the decay products of K * and ρ... more
We study the spin polarizations of both τ leptons in the decay b → sτ + τ -. In addition to the polarization asymmetries involving a single τ , we construct asymmetries for the case where both polarizations are simultaneously measured. We... more
