Andreev reflection between a normal metal and the FFLO superconductor II: a self-consistent approach
J. Kaczmarczyk, M. Sadzikowski, J. SpaÅek
We consider Andreev reflection in a two dimensional junction between a normal metal and a heavy fermion superconductor in the Fulde-Ferrell (FF) type of the Fulde-Ferrell-Larkin-Ov…
Isgur - Wise Functions for Confined Light Quarks in a Colour Electric Potential
H. Hogaasen, M. Sadzikowski
We explore the influence on the Isgur-Wise function of the colour electric potential between heavy and light quarks in mesons. It is shown that in bag models, its inclusion tends t…
Evidence for breakdown of the DGLAP description in diffractive DIS at HERA
M. Sadzikowski, L. Motyka, W. Slominski
HERA data on diffractive DIS show deviations from twist 2 DGLAP predictions below GeV at low pomeron , which may reach up to 100%. These deviations are consiste…
Meson bound states in multiflavour massive Schwinger model
M. Sadzikowski, P. Wegrzyn
The problem of meson bound states with massive fermions in two dimensional quantum electrodynamics is discussed. We speculate about the spectrum of the lightest particles by…
Comparison of the non-uniform chiral and 2SC phases at finite temperatures and densities
M. Sadzikowski
We study the phase diagram of the strongly interacting matter at finite temperatures and densities including 2SC, uniform chiral and non-uniform chiral phases within the Nambu - Jo…
Andreev reflection at QGP/CFL interface
M. Sadzikowski, M. Tachibana
In this letter we address the question of the phenomena of Andreev reflection between the cold quark-gluon plasma phase and CFL color superconductor. We show that there are two dif…
The masses of (2317) and (2463) in the MIT bag model
M. Sadzikowski
The masses of the (2317)and (2463) were found in the MIT bag model in a reasonable agreement with the experimental values. The spectrum of …
Antibaryon density in the central rapidity region of a heavy ion collision
J. Dziarmaga, M. Sadzikowski
We consider (anti-)baryons production in heavy ion collisions as production of topological defects during the chiral phase transition. Non-zero quark masses which explicitly break…
Superconducting phase transition in the Nambu - Jona-Lasinio model
M. Sadzikowski
The Nambu - Bogoliubov - de Gennes method is applied to the problem of superconducting QCD. The effective quark-quark interaction is described within the framework of the Nambu - J…
Coexistence of pion condensation and color superconductivity in two flavor quark matter
M. Sadzikowski
We show that the superconducting 2SC phase at high density and normal chiraly broken quark phase at low density is separated by the mixed non-uniform phase along the baryon density…
Semileptonic Decays of Heavy to Light Mesons from an Mit Bag Model
M. Sadzikowski
Using the (modified) MIT bag model we calculated formfactors and decay widths for pseudoscalar - pseudoscalar and pseudoscalar - vector semileptonic decays of heavy to light mesons…
Quark scattering at QGP/2SC interface
M. Sadzikowski
We considered the phenomenon of the Andreev reflection of quarks at the interface between the cold quark-gluon plasma phase and 2SC color superconductor.
Quantum radiation from spherical mirrors
L. Hadasz, M. Sadzikowski, P. Wegrzyn
We consider mirrors of the spherical shape, that can expand or contract. Due to the excitation of the vacuum around, some spherical waves radiated from vibrating mirrors are encoun…
Evidence of strong higher twist effects in diffractive DIS at HERA at moderate Q2
L. Motyka, M. Sadzikowski, W. Slominski
We study a twist decomposition of diffractive structure functions in the diffractive deep inelastic scattering (DDIS) at HERA. At low Q2 and at large energy the data exhibit a stro…
Exclusive photo- and electroproduction at HERA as a possible probe of the odderon singularity in QCD
J. Czyzewski, J. Kwiecinski, L. Motyka +1
Theory and phenomenology of the eta_c photo- and electroproduction is developed from the point of view of probing the odderon singularity in QCD which corresponds to the three gluo…
Evidence for the higher twists effects in diffractive DIS at HERA
M. Sadzikowski, L. Motyka, W. Slominski
We study a twist decomposition of diffractive structure functions in the diffractive deep inelastic scattering at HERA. At low and at large energy the data exhibit a strong d…
Isgur-Wise Functions from the Mit Bag Model
M. Sadzikowski, K. Zalewski
The Isgur-Wise functions for the ground state to ground state semileptonic decays involving transitions are calculated from the (modified) MIT bag model. It is ch…
