We show that if {Ln} is any infinite sequence of links with
twist number τ(Ln) and with cyclotomic Jones
polynomials of increasing span, then
lim sup τ(Ln)=∞. This implies that any infinite
sequence of prime alternating links with cyclotomic Jones polynomials
must have unbounded hyperbolic volume. The main tool is the
multivariable twist–bracket polynomial, which generalizes
the Kauffman bracket to link diagrams with open twist sites.
