Уважаемые коллеги!

На заседании Ученого совета ИТФ в пятницу 31.01 в 11:30 будут заслушаны 2 доклада:
1). Б.Г. Захаров
Effect of color randomization on p_T broadening of fast partons in turbulent quark-gluon plasma

We analyze the effect of the parton color randomization on p_T broadening
in the quark-gluon plasma with turbulent color fields. We calculate the
transport coefficient qhat for a simplified model of fluctuating color
fields in the form of alternating sequential transverse layers with homogenous
transverse chromomagnetic fields with random orientation in the
SU(3) group and gaussian distribution in the magnitude. Our numerical
results show that the color randomization can lead to a sizable reduction of
the turbulent contribution to qhat. The magnitude of the effect grows
with increasing ratio of the electric and magnetic screening masses.

2). Б.Г. Захаров
Jet quenching for hadron-tagged jets in pA collisions

We calculate the medium modification factor I_pA
for 5.02 TeV p+Pb collisions. We use the Monte-Carlo Glauber model to
determine the parameters of the quark-gluon plasma fireball in pA
jet events. Our calculations show that the jet quenching effect for I_pA
turns out to be rather small. We have found that the theoretical I_pA as
a function of the underlying event charged multiplicity density, within errors,
agrees with data from ALICE for 5.02 TeV p+Pb collisions. However,
the experimental errors are too large to draw a firm conclusion on the possible presence of jet quenching.

NASA honors fallen astronauts with 'Day of Remembrance' ceremony

NASA honors fallen astronauts on 'Day of Remembrance' | Space Quiz! What are the fastest wind speeds recorded on an exoplanet? | This Week In Space: 'Star Bound' - The US space program Created for znamenski.spacecom@blogger.com |  Web Version January 27, 2025 CONNECT WITH SPACE.COM       Something amazing every day. SIGN UP ⋅   WEBSITE   The Launchpad NASA honors fallen astronauts on 'Day of Remembrance' (NASA) NASA honored its fallen space explorers during its annual "Day of Remembrance" on Thursday (Jan. 23). The agency held events at a number of its facilities around the nation, including Kennedy Space Center (KSC) in Florida and Johnson Space Center in Houston. The proceedings commemorated the lives lost in NASA's three space tragedies - the Apollo 1 fire in January 1967, the space shuttle Challenger explosion in January 1986 and the shuttle Columbia disaster in February 2003.
