We present the first measurements of the e[over -->]p-->epgamma cross section in the deeply virtual Compton scattering (DVCS) regime and the valence quark region. The Q(2) dependence (from 1.5 to 2.3 GeV(2)) of the helicity-dependent cross section indicates the twist-2 dominance of DVCS, proving that generalized parton distributions (GPDs) are accessible to experiment at moderate Q(2). The heli...
It is known that the large-$q$ complex Sachdev-Ye-Kitaev (SYK) dot thermalizes instantaneously under rather general dynamical protocols. We consider a lattice of such dots coupled together, allowing for $r/2$ body hopping particles between nearest neighbors. develop analytical framework to study dynamics leading order in $1/q$ on lattice, arbitrary time dependent couplings, hence find physics d...
Define a (pre)order on /3co as follows: p • q iff there is a finite to one function f c woo such that/3f(cl) = p. Let ,•{ denote he Rudin-Keisler order on Ow. We show that here are points p,qCw* such that Px•q, but p and q are •<-incomparable. 0. Introduction. In [5], M. E. Rudin showed that if there are points p,q G co* Such that for any finite to one function f G cow we have that 13f(p) 4:13f...
We exhibit a genus–2 curve C defined over Q(T ) which admits two independent morphisms to a rank–1 elliptic curve defined over Q(T ). We describe completely the set of Q(T )–rational points of the curve C and obtain a uniform bound for the number of Q–rational points of a rational specialization Ct of the curve C for a certain (possibly infinite) set of values t ∈ Q. Furthermore, for this set o...
We consider a variant of the charge-Q compact Abelian-Higgs model, in which an Nf-dimensional complex vector is coupled with Abelian Z_q gauge field. For Nf=2 and Q=1 we observe several transition lines that belong to O(4), O(3), O(2) universality classes, depending on symmetry breaking pattern at transition. The class independent $q$ as long q>=3. uniquely determined by behavior scalar fields;...
Despite large uncertainties in the W ± and Z 0 transverse momentum (q T) distributions for q T < ∼ 10 GeV, the ratio of the distributions varys little. The uncertainty in the ratio of W to Z q T distributions is on the order of a few percent, independent of the details of the nonperturbative parameterization.
The average cost of Duval's algorithm for generating all Lyndon words up to a given length in lexicographic order is proved to be asymptotically equal to (q + 1)=(q ? 1), where q is the size of the underlying alphabet. In particular, the average cost is independent of the length of the words generated. A precise evaluation of the constants is also given.
In his study of partitions without k-sequences, Andrews proved a double hypergeometric q-series representation of the generating series and a corresponding k-term q-difference equation. In this note we give new proofs of the double series formula, as well as a new two-term q-difference equation. In both cases, we provide independent analytic and combinatorial proofs.
Let P and Q be finite sets of points in the plane. In this note we consider the largest cardinality of a subset of the Minkowski sum S ⊆ P ⊕ Q which consist of convexly independent points. We show that, if |P | = m and |Q| = n then |S| = O(m2/3n2/3 + m + n).
Nonimprovable, in general, estimates of the number of necessary and sufficient conditions for two Hermitian operators to be unitarily equaivalent in a unitary space are obtained when the multiplicities of eigenvalues of operators can be more than 1. The explicit form of these conditions is given. In the Appendix the concept of conditionally functionally independent functions is given and the co...
