We report on the first measurement of charm-strange meson Ds± production at midrapidity in Au+Au collisions at sNN=200 GeV from the STAR experiment. The yield ratio between strange (Ds±) and nonstrange (D0) open-charm mesons is presented and compared to model calculations. A significant enhancement, relative to a pythia simulation of p+p collisions, is observed in the Ds±/D0 yield ratio in Au+Au collisions over a large range of collision centralities. Model calculations incorporating abundant strange-quark production in the quark-gluon plasma and coalescence hadronization qualitatively reproduce the data. The transverse-momentum integrated yield ratio of Ds±/D0 at midrapidity is consistent with a prediction from a statistical hadronization model with the parameters constrained by the yields of light and strange hadrons measured at the same collision energy. These results suggest that the coalescence of charm quarks with strange quarks in the quark-gluon plasma plays an important role in Ds±-meson production in heavy-ion collisions. © 2021 authors.

With the onset of the COVID-19 pandemic and the ensuing shutdown of the library building for several months, there was a sudden need to adjust how the Hilton C. Buley Library at Southern Connecticut State University (SCSU) delivered its services. Overnight, the library’s virtual chat service went from a convenient way to reach a librarian to the primary method by which library patrons contacted the library for help. In this article, the authors will discuss what was learned during this time and how the service has been adjusted to meet user needs. Best practices and future improvements will be discussed.

From the epic saga of the Buendía family in One Hundred Years of Solitude to the enduring passion of Love in the Time of Cholera to the exploration of tyranny in The Autumn of the Patriarch, Gabriel García Márquez has built a literary world that continues to captivate millions of readers across the world. His writings entrance modern audiences with their dreamlike yet trenchant insights into universal issues of the human condition such as love, revenge, old age, death, fate, power, and justice. A Nobel Laureate in 1982, he contributed to the global popularity of the Latin American Boom during the second half of the 20th century and had a profound impact on writers worldwide, including Toni Morrison, Salman Rushdie, and Haruki Murakami. The Oxford Handbook of Gabriel García Márquez brings together world experts on the Colombian writer to present a comprehensive English-language examination of his life, oeuvre, and legacy--the first such work since his death in 2014. Edited by Latin American literature authorities Gene H. Bell-Villada and Ignacio López-Calvo, the volume paints a rich and nuanced portrait of "Gabo." It incorporates ongoing critical approaches such as feminism, ecocriticism, Marxism, and ethnic studies, while elucidating key aspects of his work, such as his Caribbean-Colombian background; his use of magical realism, myth, and folklore; and his left-wing political views. Thirty-two wide-ranging chapters cover the bulk of the author's writings-both major and minor, early and late, long and short-as well as his involvement with film. They also discuss his unique prose style, highlighting how music shaped his literary art. The Handbook gives unprecedented attention to the global influence of García Márquez-on established canons, on the Global South, on imaginative writing in South Asia, China, Japan, and throughout Africa and the Arab world. This is the first book that places the Colombian writer within that wider context, celebrating his importance both as a Latin American author and as a global phenomenon.

We report on the W and Z/γ∗ differential and total cross sections as well as the W+/W− and (W++W−)/(Z/γ∗) cross section ratios measured by the STAR experiment at RHIC in p+p collisions at √s=500 GeV and 510 GeV. The cross sections and their ratios are sensitive to quark and antiquark parton distribution functions. In particular, at leading order, the W cross section ratio is sensitive to the ¯d/¯u ratio. These measurements were taken at high Q2∼M2W,M2Z and can serve as input into global analyses to provide constraints on the sea quark distributions. The results presented here combine three STAR datasets from 2011, 2012, and 2013, accumulating an integrated luminosity of 350 pb−1. We also assess the expected impact that our W+/W− cross section ratios will have on various quark distributions, and find sensitivity to the ¯u−¯d and ¯d/¯u distributions.

Nonmonotonic variation with collision energy (sNN) of the moments of the net-baryon number distribution in heavy-ion collisions, related to the correlation length and the susceptibilities of the system, is suggested as a signature for the quantum chromodynamics critical point. We report the first evidence of a nonmonotonic variation in the kurtosis times variance of the net-proton number (proxy for net-baryon number) distribution as a function of sNN with 3.1 σ significance for head-on (central) gold-on-gold (Au+Au) collisions measured solenoidal tracker at Relativistic Heavy Ion Collider. Data in noncentral Au+Au collisions and models of heavy-ion collisions without a critical point show a monotonic variation as a function of sNN. © 2021 American Physical Society.
