   Dear Mary Kihanya,

  Here is a copy of the letter I mailed you on Thursday the 11th.  In
addition I can definitely say that I only need a hotel room for Sunday,
Monday and Tuesday evenings.  I'm not sure why you didn't receive the
first mail. Please, respond to this mail so that I know you've received
it.

   Dear Mary Kihanya,

  Thank you for the information you sent me.  Here are the answers to
the questions you asked.

Flight information:

Arrive Fri June 19 11:58 AM United Flight 1733Q Oakland Terminal 1
Depart Wed June 24 06:15 Am United Flight 1097Q Oakland Terminal 1
Fare $374.00
If you want I can fax the ticket information to you, if that will help
with the reimbursement.  Also, I am a US citizen.

Ground Transport
I would appreciate ground transport to and from the University.

Lodging
My brother lives in the Bay area and I hope to stay with him over the
weekend.  Perhaps, you could wait one day before booking lodging while
I contact him.  However, I will definitely need a room near the university
for Sunday, Monday and Tuesday evenings.

Seminar
Study of B_c Meson with the OPAL Detector at LEP

A search for decays of the $B_c$ meson was performed using data collected
from 1990--1995 with the OPAL detector on or near the $Z^0$ peak at LEP.
The decay channels $B_c^+\rightarrow J/\psi\pi^+$, $B_c^+\rightarrow
J/\psi a_1^+$ and $B_c^+\rightarrow J/\psi\ell^+\nu$ were investigated,
where $\ell$ denotes an electron or a muon. Two candidates are observed in
the mode $B_c^+\rightarrow J/\psi\pi^+$, with an estimated background of
$(0.63\pm 0.20)$ events. The weighted mean of the masses of the two
candidates is $(6.32\pm 0.06)$~$GeV/c^2$, which is consistent with the
predicted mass of the $B_c$ meson. One candidate event is observed in the
mode $B_c^+\rightarrow J/\psi\ell^+\nu$, with an estimated background of
$(0.82\pm 0.19)$ events.  No candidate events are observed in the
$B_c^+\rightarrow J/\psi a_1^+$ decay mode, with an estimated background
of $(1.10\pm 0.22)$ events. Upper bounds at the 90\% confidence level are
set on the production rates for these processes.
