Stability of a high Mach number flow in a channel
M. Deka, G. Tomar, V. Kumaran
Modal instabilities in a flow through a channel at high Reynolds and Mach numbers are studied for three-dimensional perturbations. In addition to the Tollmien-Schlichting modes, th…
On the physics potential to study the gluon content of proton and deuteron at NICA SPD
A. Arbuzov, A. Bacchetta, M. Butenschoen +25
The Spin Physics Detector (SPD) is a future multipurpose experiment foreseen to run at the NICA collider, which is currently under construction at the Joint Institute for Nuclear R…
Implications of a turbulent convection model for classical Cepheids
M. Deka, F. Ahlborn, T. A. M. Braun +1
The appearance of blue loops in the evolutionary tracks of intermediate-mass core He-burning stars is essential for explaining the observed characteristics of Cepheids. The blue lo…
Nucleon mass and sigma term from lattice QCD with two light fermion flavors
G. S. Bali, P. C. Bruns, S. Collins +16
We analyze Nf=2 nucleon mass data with respect to their dependence on the pion mass down to mpi = 157 MeV and compare it with predictions from covariant baryon chiral perturbation…
A Lattice Study of Quark and Glue Momenta and Angular Momenta in the Nucleon
M. Deka, T. Doi, Y. B. Yang +10
We report a complete calculation of the quark and glue momenta and angular momenta in the proton. These include the quark contributions from both the connected and disconnected ins…
The light curve model fitting of LMC Cepheids: MESA-RSP versus Stellingwerf's code predictions
M. Deka, M. Marconi, R. Molinaro +9
A major challenge in modeling classical Cepheids is the treatment of convection, particularly its complex interplay with pulsation. This inherently three-dimensional process is typ…
Quark and Glue Momenta and Angular Momenta in the Proton --- a Lattice Calculation
K. F. Liu, M. Deka, T. Doi +10
We report a complete calculation of the quark and glue momenta and angular momenta in the proton. These include the quark contributions from both the connected and disconnected ins…
Moments of Nucleon's Parton Distribution for the Sea and Valence Quarks from Lattice QCD
M. Deka, T. Streuer, T. Doi +5
We extend the study of lowest moments, and , of the parton distribution function of the nucleon to include those of the sea quarks; this entails a disconnected inserti…
