A Difference Operator Approach to Quantum Random Walks: Parseval Identity, Krawtchouk Matrices, and Hermite Limits
Chien-Wen Hwang
We introduce a discrete difference operator D_k to study the one-dimensional quantum random walk (QRW) with the Hadamard coin. Explicit combinatorial expressions are obtained for t…
Three symmetry breakings in strong and radiative decays of strange heavy mesons
Chi-Yee Cheung, Chien-Wen Hwang
In this paper, we investigate three symmetry breaking effects in strong and radiative decays of strange heavy mesons. We study 1/m_Q corrections within the heavy quark effect theor…
Strong and radiative decays of heavy mesons in a covariant model
Chi-Yee Cheung, Chien-Wen Hwang
In this paper, we investigate symmetry breaking effects in strong and radiative decays of heavy mesons. We study corrections within the heavy quark effective theory. These…
Study of light-cone distribution amplitudes for p-wave heavy mesons
Chien-Wen Hwang
In this paper, a study of light-cone distribution amplitudes for p-wave heavy mesons is presented in both general and heavy quark frameworks. Within the light-front approach, the l…
Meson distribution amplitudes in holographic models
Chien-Wen Hwang
We study the wave functions of light and heavy mesons in both hard-wall (HW) and soft-wall (SW) holographic models which use AdS/CFT correspondence. In the case of massless constit…
Two-photon and two-gluon decays of p-wave heavy quarkonium using a covariant light-front approach
Chien-Wen Hwang, Rurng-Sheng Guo
In this paper, a study of two-photon and two-gluon decays in the context of p-wave heavy quarkonia is presented. Within the covariant light-front framework, the annihilation rates…
