Sign changes of Kloosterman sums with almost prime moduli

We prove that the Kloosterman sum changes sign infinitely often as runs over squarefree moduli with at most 10 prime factors, which improves the previous results of Fouvry and Michel, Sivak-Fischler and Matomaki, replacing 10 by 23, 18 and 15, respectively ...

Equality between Monge and Kantorovich multimarginal problems with Coulomb cost

Maria Colombo

A standard question arising in optimal transport theory is whether the Monge problem and the Kantorovich relaxation have the same infimum; the positive answer means that we can pass to the relaxed problem without loss of information. In the classical case ...

Measurements of B -> (D)over-barDs0(+)(2317) decay rates and a search for isospin partners of the Ds0(+)(2317)

Olivier Schneider, Mingkui Wang, Chao Wang, Tagir Aushev, Ho Ling Li, Sun Hee Kim, Tara Nanut, Jun Yong Kim, Ji Hyun Kim, Donghyun Kim, Dipanwita Dutta, Xiao Wang

We report improved measurements of the product branching fractions B(B+ --> (D) over bar D-0(s0)(+)(2317)) x B(D-s0(+)(2317) --> D-s(+) pi(0)) (8.0(-1.2)(+1.3) +/- 1.1 +/- 0.4) x 10(-4) and B(B-0 --> D-Ds0*(+)(2317)) x B(D-s0*(+)(2317)) --> D-s(+) pi(0)) ...

Cyclic Hypervalent Iodine Reagents and Pd-Catalysis

Maria Victoria Vita

Developing new strategies and methods to explore new dimensions of the chemical space represents an important goal for organic chemists. One particular synthetic approach that emerged in the last decades is Umpolung: the normal polarity of chemical functio ...

Algebraic Divisibility Sequences Over Function Fields

Valéry Aurélien Mahé

In this note we study the existence of primes and of primitive divisors in function field analogues of classical divisibility sequences. Under various hypotheses, we prove that Lucas sequences and elliptic divisibility sequences over function fields define ...

Study of B-+/- -> K-+/-(KSK pi)(0) decay and determination of eta(c) and eta(c)(2S) parameters

Olivier Schneider, Yiming Li, Chao Wang, Tagir Aushev, Vladislav Balagura, Remi Léandre Albert Louvot, Jing Li

We report the results of a study of B KIrk and /II K tic(2S) decays followed by qc and '/c(2S) decays to (K5K7). The results are obtained from a data sample containing 535 million BB-meson pairs collected by the Belle experiment at the KEKB e+e- collider. ...

Bounds on the width, mass difference and other properties of X(3872) -> pi(+)pi(-) J/psi decays

Olivier Schneider, Yiming Li, Aurelio Bay, Mingkui Wang, Chao Wang, Tagir Aushev, Sun Hee Kim, Jun Yong Kim, Remi Léandre Albert Louvot, Ji Hyun Kim, Xiao Wang, Jing Li, Xuan Li

We present results from a study of X(3872) -> pi pi J/psi decays produced via exclusive B -> KX(3872) decays. We determine the mass to be M-X(3872) = (3871.85 +/- 0.27(stat) +/- 0.19(syst)) MeV, a 90% confidence level upper limit on the natural width of Ga ...

Stereoselective syntheses of polyhydroxylated azepane derivatives from sugar-based epoxyamides. Part 1: synthesis from D-mannose

Pierre Vogel, Claudia Bello

An approach to the synthesis of polyhydroxyazepane derivatives from sugar-based epoxyamides or epoxyalcohols, in which the total regioselective epoxide opening by nitrogen nucleophiles is the key step, is described. Thus, novel polyhydroxyazepane carboxami ...

Search for charmonium and charmoniumlike states in Υ(1S) radiative decays

Olivier Schneider, Mingkui Wang, Chao Wang, Tagir Aushev, Vladislav Balagura, Remi Léandre Albert Louvot, Xiao Wang, Jing Li

Using a sample of 102 X 10(6) Y(1S) events collected with the Belle detector, we report on the first search for charge-parity-even charmonium and charmoniumlike states in Y(1S) radiative decays. No significant chi(cJ) or eta(c) signal is observed and 90% C ...

Ideal knots and other packing problems of tubes

Henryk Gerlach

This thesis concerns optimal packing problems of tubes, or thick curves, where thickness is defined as follows. Three points on a closed space curve define a circle. Taking the infimum over all radii of pairwise-distinct point triples defines the thickness ...
