Medium modification of pseudoscalar meson structure: Distribution amplitudes and parton distribution functions
Muhammad Ridwan, Parada Tobel Paraduan Hutauruk, Ahmad Jafar Arifi +1
In this work, we present a comprehensive investigation of the in-medium properties and internal structure of pseudoscalar mesons within the light-front quark model (LFQM), employin…
Electromagnetic structure of strange vector mesons in nuclear medium
Parada T. P. Hutauruk, Terry Mart, Kazuo Tsushima
We investigate the in-medium modifications of the charge (electric) , magnetic , and quadrupole form factors of the positively charged ve…
Polarization-dependent mass modifications of meson with finite momentum in nuclear matter
Ahmad Jafar Arifi, Philipp Gubler, Kazuo Tsushima
We investigate the in-medium properties of the meson with finite momentum, going beyond the commonly studied case at rest. In a nuclear medium, Lorentz invariance is broken, le…
Octet baryon electroweak form factors in dense nuclear matter
G. Ramalho, K. Tsushima, Myung-Ki Cheoun
Motivated by the necessity of developing theoretical models for studying the electroweak structure of baryons in a nuclear medium, we apply a covariant quark model to study interac…
In-medium mass shifts of and mesons
K. Tsushima, S. L. P. G. Beres, G. N. Zeminiani
We present our predictions for the Lorentz scalar mass shifts of two-flavored heavy mesons, and in symmetric nuclear matter. The in-medium mass s…
Heavy-heavy and heavy-light mesons in cold nuclear matter
J. J. Cobos-Martínez, Guilherme N. Zeminiani, Kazuo Tsushima
We review the in-medium modifications of effective masses (Lorentz scalar potentials or phenomenon of mass shift) of heavy-heavy and heavy-light mesons in symmetric nuclear matter…
In-medium electromagnetic form factors of pseudoscalar mesons from the quark model
Ahmad Jafar Arifi, Parada T. P. Hutauruk, Kazuo Tsushima
We explore the modifications of hadron structure in a nuclear medium, focusing on the spacelike electromagnetic form factors (EMFFs) of light and heavy-light pseudoscalar mesons. B…
Kaon Structure in the Nuclear Medium within the Light Front Approach
G. H. S. O. Yabusaki, J. P. B. C. de Melo, K. Tsushima +2
We study the properties of the charged kaon in symmetric nuclear matter using a Bethe-Salpeter amplitude to model the quark-anti-quark bound state, which is well constrained by pre…
In-medium rho-meson properties in a light-front approach
J. P. B. C. de Melo, K. Tsushima
Properties of \r{ho}-meson in symmetric nuclear matter are investigated within a light-front constituent quark model (LFCQM), using the in-medium input calculated by the quark-meso…
In-Medium Pion Valence Distributions in a Light-Front Model
J. P. B. C de Melo, K. Tsushima, I. Ahmed
Pion valence distributions in nuclear medium and vacuum are studied in a light-front constituent quark model. The in-medium input for studying the pion properties is calculated by…
Octet baryon electromagnetic form factors in nuclear medium
G. Ramalho, K. Tsushima, A. W. Thomas
We study the octet baryon electromagnetic form factors in nuclear matter using the covariant spectator quark model extended to the nuclear matter regime. The parameters of the mode…
Octet baryon electromagnetic form factors in a relativistic quark model
G. Ramalho, K. Tsushima
We study the octet baryon electromagnetic properties by applying the covariant spectator quark model, and provide covariant parametrization that can be used to study baryon electro…
A simple relation between the gamma N -> N(1535) helicity amplitudes
G. Ramalho, K. Tsushima
It is shown that the helicity amplitudes A_1/2 and S_1/2 in the gamma N -> N(1535) reaction, can be well related by S_1/2 = -\frac{\sqrt{1+τ}}{\sqrt{2}} \frac{M_S^2-M^2}{2 M_S Q} A…

We derive the formal expressions needed to discuss the change of the twist-two parton distribution functions when a hadron is placed in a medium with relativistic scalar and vector…
Baryon Masses from Lattice QCD: Beyond the Perturbative Chiral Regime
D. B. Leinweber, A. W. Thomas, K. Tsushima +1
Consideration of the analytic properties of pion-induced baryon self-energies leads to new functional forms for the extrapolation of light baryon masses. These functional forms rep…
