Neutrino Majorna masses from string theory instantons

Abstract
I discuss the uncertainties on predictions at the LHC due to our current level of  understanding of Standard Model physics, pointing out that these are often greater than the standard quoted results. I highlight both the experimental measurements and improved theoretical treatments which are necessary to fill in the gaps and maximise the precision of our predictions for both Standard Model and Beyond the Standard Model processes at the LHC.

Fluctuations of the front in a one dimensional growth model

Prof Francis Comets
(University of Paris VII)
Abstract

We report on two joint works with Jeremy Quastel and Alejandro Ramirez, on an

interacting particle system which can be viewed as a combustion mechanism or a

chemical reaction.

We consider a model of the reaction $X+Y\to 2X$ on the integer lattice in

which $Y$ particles do not move while $X$ particles move as independent

continuous time, simple symmetric random walks. $Y$ particles are transformed

instantaneously to $X$ particles upon contact.

We start with a fixed number $a\ge 1$ of $Y$ particles at each site to the

right of the origin, and define a class of configurations of the $X$ particles

to the left of the origin having a finite $l^1$ norm with a specified

exponential weight. Starting from any configuration of $X$ particles to the left

of the origin within such a class, we prove a central limit theorem for the

position of the rightmost visited site of the $X$ particles.
